Suez Canal, Sumed Pipeline are key parts of Egypt's role in international energy markets

Egypt plays a vital role in international energy markets through the operation of the Suez Canal and Suez-Mediterranean (Sumed) Pipeline. In 2012, about 7% of all seaborne traded oil and 13% of liquefied natural gas (LNG) traded worldwide transited through the Suez Canal. Egypt's 2011 revolution and the unrest that has followed have not had any noticeable effect on oil and LNG transit flows through the Suez Canal or Sumed Pipeline.

Graph of Suez and SUMED pipeline flows, as explained in the article text Source: Suez Canal Authority (with EIA conversions) and EIA analysis based on APEX Tanker Data.

The Suez Canal is an important transit route for oil and LNG shipments traveling northbound from the Persian Gulf to Europe and North America and southbound from North Africa and countries along the Mediterranean Sea to Asia. Changes to total oil and LNG flows through the Suez Canal in 2012 mainly occurred because of events outside of Egypt, particularly the restart of Libyan oil production and changing dynamics in LNG markets. Further, the Sumed Pipeline is the only alternative route nearby to transport crude oil northbound if loaded tankers are too large or ride too low in the water to navigate through the Suez Canal.


Oil flows. In 2012, southbound oil flows reached a record high as Libyan oil shipments through the Suez Canal quadrupled in 2012 compared with the previous year, reflecting the ramp-up of Libyan oil production after its civil war. In 2012, about 2.97 million barrels per day (bbl/d) of total oil (crude oil and refined products) transited the Suez Canal in both directions. This is the highest amount ever shipped through the Suez Canal, and made up about 7% of total seaborne traded oil. Crude oil flows through Sumed decreased in 2012 to 1.54 million bbl/d, as more crude oil was shipped through the Suez Canal via tankers.


LNG flows. Total Suez LNG flows as a percentage of total LNG traded worldwide fell to 13%, or 1.5 trillion cubic feet, in 2012, compared with 18% in 2011 for two main reasons. First, northbound LNG flows through the Suez Canal fell by nearly one-third in 2012 largely because of decreased LNG exports from Qatar to the United States and Europe. Second, northbound flows also fell because of reduced LNG exports from Yemen as a result of sabotage attacks on a gas pipeline.


Supply chain. Although external factors have to this point played a larger role in altering hydrocarbon flows through Egypt's transit points, unrest in Egypt still presents a risk, and the Egyptian army continues to guard the Suez Canal. Closure of the Suez Canal and the Sumed Pipeline would necessitate diverting oil tankers around the southern tip of Africa, the Cape of Good Hope. That would add 2,700 miles to ship oil from Saudi Arabia to the United States, increasing both costs and shipping time, according to the U.S. Department of Transportation. Moreover, shipping around Africa would add 15 days of transit to Europe and 8-10 days to the United States, according to the International Energy Agency.


Oil and natural gas production. Egypt's oil and gas production has largely been unaffected by the social unrest. The most visible effect of the revolution on Egypt's energy sector has been a series of attacks on the Arab Gas Pipeline that contributed to a significant drop in the country's pipeline gas exports. In addition, growing local demand for oil and gas amid stagnant production has led to energy shortages, contributing to continued protests and sporadic unrest in the country.

What are the major sources and users of energy in the United States?


The major energy sources in the United States are petroleum (oil), natural gas, coal, nuclear, and renewable energy. The major users are residential and commercial buildings, industry, transportation, and electric power generators. The pattern of fuel use varies widely by sector. For example, oil provides 93% of the energy used for transportation, but only about 1% of the energy used to generate electric power. Understanding the relationships between the different energy sources and their uses provides insights into many important energy issues.


Primary energy includes petroleum, natural gas, coal, nuclear fuel, and renewable energy. Electricity is a secondary energy source that is generated from these primary forms of energy.


Primary energy sources are commonly measured in different units: barrels (= 42 gallons) of oil, cubic feet of natural gas, tons of coal. To compare across fuels, we need to use a common unit of measure. The United States uses Btu, or British thermal units, which measure fuel use by the energy content of each fuel source.


Total U.S. energy use in 2011 was about 97.5 quadrillion (=1015, or one thousand trillion) Btu. One quadrillion Btu, often referred to as a "quad," therefore represents about 1% of total U.S. energy use.


In physical energy terms, 1 quad represents 172 million barrels of oil (about 10 days of U.S. oil use), 50 million tons of coal (enough to generate about 3% of annual U.S. electricity use), or about 1 trillion cubic feet of natural gas (equal to 4% of annual U.S. natural gas use in 2011).


The number of quads used in 2011 from each primary energy source is shown in the pie chart on the left. Petroleum (oil) provides the largest share of U.S. primary energy, followed by natural gas, coal, nuclear energy, and renewable energy (including hydropower, solar, geothermal, wind, and biomass).


Primary energy is used in residential and commercial buildings (including homes, businesses, schools, and churches), in transportation, and by industry. Primary energy is also used to generate electricity. The bar chart shows the amount of primary energy used in each of these sectors. As you can see, electric power generation is the largest user of primary energy, followed by transportation.


The electric power sector uses primary energy to generate electricity, which makes electricity a secondary, rather than a primary, energy source. Nearly all electricity is then used in buildings and by industry. This means that the total levels of energy used by residential and commercial buildings, industry, and transportation are actually higher than the amounts shown on the graphics when electricity is added in.


The lines in the figure below connecting the primary-energy-sources on the left with the demand-sectors on the right summarize the source-sector linkages in the U.S. energy system. For example, because all nuclear energy is used in the electric power sector to generate electricity, and nuclear represents 21% of the primary energy used by that sector, the line between nuclear energy and the electric power sector shows 100% on the nuclear (supply source) side and 21% on the electric power (demand sector) side.

Chart showing U.S. primary energy consumption by source and sector for 2011 in quadrillion Btu. Total consumption in 2011 was 97.5 quadrillion Btu. Source: U.S. Energy Information Administration, Annual Energy Review 2010.

The mix of primary energy sources varies widely across demand sectors. Energy policies designed to influence the use of a particular primary fuel for environmental, economic, or energy security reasons often focus on sectors that are major users of that fuel.


For example, because 71% of petroleum (oil) is used in the transportation sector, where it provides 93% of the total energy used, policies to reduce oil consumption have tended to focus on the transportation sector. These policies usually seek to increase fuel efficiency or promote alternative fuels. Ninety-one percent of coal, but only 1% of oil, is used to generate electricity, suggesting that policies affecting electricity generation are likely to have a much larger impact on coal use than oil use.


Some primary energy sources, such as nuclear and coal, are entirely or predominately used in one sector. Others, like natural gas and renewables, are more evenly distributed across sectors. Similarly, while transportation is almost entirely dependent on one fuel (oil), electric power uses a variety of fuels.


Linkages between fuels and sectors can and do change over time, but the change tends to occur slowly. For example, coal was once used extensively as a fuel for heating homes and commercial buildings, but that use has dwindled to almost nothing in the United States over the past half-century. Although renewable energy is still relatively small as a share of total primary energy in the transportation and electric power sectors, its role has been growing.

How can we compare or add up our energy consumption?


To compare or aggregate energy consumption across different energy sources like oil, natural gas, and electricity, we must use a common unit of measure. This is similar to calculating your food energy intake by adding up the calories in whatever you eat.


In American households we use several kinds of energy. It's difficult to add up or compare the total energy we use because each energy source is typically measured in a different unit: gasoline is usually measured in gallons, electricity in kilowatthours, and natural gas in cubic feet. One way to add and compare different energy sources is to convert them all to a common unit of measure based on their energy content.


One Btu is the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit. It is approximately equal to the amount of energy that comes from burning one wooden kitchen match. A Btu isn't an everyday term to most people, but you might see it on your energy bill or in a news article.


Because a Btu is such a small unit of energy, there are tens of thousands of Btus in even one gallon of gasoline. The table to the right shows how to convert different energy sources into Btus.


You probably already have experienced converting physical units to energy units. When calculating the total amount of food you eat, you might look up how many calories are in each item and then add up the calories. You can't add a hamburger and a soft drink without the conversion. So you can see that calories are a common unit for measuring the energy content of food.

photo of hamburger and fries Let's say you consume a typical fast-food meal of:

If you ate the items listed above, you would have consumed 900 calories. Just as calories are a useful measure to help you compare different food items, Btus are useful for making energy comparisons.


If you want to calculate the total amount of energy you use, the process is similar. You can take the gallons of gasoline consumed by your car, the amount of natural gas and other fuels that heat your home, and the kilowatthours of electricity to run your lights and appliances, and convert them all to Btu equivalents using the conversion rates in the table. Then you can add up the different pieces to get a total amount in common units.


One wrinkle is that electricity is an energy carrier, or secondary fuel source, rather than a primary fuel source. There are significant losses in the conversion of primary fuels to electricity and in the transmission and distribution of electricity to the consumer.


For example, in 2011 the average coal-fired plant used 10,400 Btu of coal to generate one kilowatt hour (=3,412 Btu) of electricity. (Of course, there are regional differences in the primary energy used to generate electricity, and not all generation comes from thermal sources with the associated thermal energy losses.) In addition, another 7-8% of the electricity is used up when it is transmitted and distributed from the power plant to your house. If your focus is on primary energy use (such as coal, natural gas, or oil), you should start your calculation with the energy used to make and deliver electricity instead of the energy in the electricity itself.


Most people are interested in saving energy these days, and you can use Btu equivalents to help compare the different levels of savings resulting from taking different actions or making various lifestyle changes. Which do you think uses more energy in a year: gasoline in the average car or electricity in the average home? It's easy to find the answer if you make some assumptions about average usage and then convert the numbers to Btu. See the answers below.


It's interesting to see in these comparisons that residential use of energy for electricity appears to be lower than that for an average vehicle when you use the consumption Btu value of 3,412 Btu per kWh for electricity. But if you count all the primary energy used to generate and deliver the electricity, average residential use of energy for electricity is actually much higher than it is for a single vehicle. However, nearly 60% of households have two or more vehicles, making the average household use of energy for electricity about the same as it is for two passenger vehicles.


Here's another way to compare energy use. Suppose you hear about a new energy efficiency proposal that will save 1,000 trillion Btu per year, which is about 1% of total U.S. annual energy use. A trillion is a big number to visualize. However, sometimes it's easier to appreciate how much energy is represented by thinking in terms of cars or houses, just like it's easier to think of calories as hamburgers and fries, not the calories themselves.


You could divide the energy used by one car/vehicle (66 million Btu) into 1,000 trillion Btu to find that the energy savings in the same proposal described above is equal to taking approximately 15.2 million vehicles off the roads. These averages provide a way to visualize and understand the magnitude of the energy issues and solutions being considered.


The average passenger car/vehicle (including light trucks, vans, and sport utility vehicles) in the United States uses about 66 million Btu per year, which sounds like a big number for just one vehicle. But total energy use for cars, light trucks, vans, and sport utility vehicles in 2010 was about 15 quadrillion Btu, which is 15 with 15 zeros added on to it. That was equivalent to about 16% of total U.S. energy consumption in 2010.


Energy sources are expressed in different units, but their energy content can be compared using the British thermal unit (Btu)

Conversion Table of Common Energy Sources to Btu Energy SourcePhysical Units and Btu Equivalents1 kilowatthour (kWh) = 3,412 Btu (but on average, it takes about 3 times the Btu of primary energy to generate the electricity)1 cubic foot (ft3) = 1,022 Btu
1 cubic foot = 0.01 therms

What were the key energy commodity price trends in 2012?

Image of bar chart showing select commodity price changes between Jan 1 and Dec 31, 2011, as described in the article text. Source: U.S. Energy Information Administration based on Bloomberg, L.P.
Note: Price changes are derived by taking the difference in prompt contract price for each commodity between January 1 and December 31, 2012. This method allows for comparisons of different commodity classes on a consistent basis. PRB Coal is Powder River Basin Coal. CAPP Coal is Central Appalachia Coal. WTI is West Texas Intermediate, a benchmark for both physical and financial crude oil pricing located in Cushing, Oklahoma. RBOB Gasoline is a kind of gasoline based on a reformulated blendstock for oxygenate blending (RBOB).

Coal and mid-continent crude oil (WTI) led energy commodity price declines in 2012. Natural gas was the only key energy commodity with a significant price increase when comparing January 1 to December 31. Heating oil, Brent crude oil, and wholesale gasoline (RBOB) ended 2012 close to the level at which they started the year(see graphs, right side).


In 2012, average prices for crude oil and petroleum products were largely close to the 2011 averages, with some fluctuations throughout the year. Natural gas prices declined through the early portion of 2012 but then increased in the early fall and winter. Prices for Central Appalachian (CAPP) and Powder River Basin (PRB) coal declined at the beginning of 2012 and remained significantly below the average levels of 2011.


This article provides an overview of a series of related articles (see Today in Energy, 2012 Briefs) on energy market trends in 2012. To ensure comparability among commodities, the prices shown here reflect near-month contracts of futures prices. Most other articles in this series focused on spot market trends. Some key findings from these articles include:


Crude oil and petroleum products

Brent crude oil averaged $111.67 per barrel in 2012, edging past last year's average price of $111.26 per barrel and marking the second year in a row that the global oil benchmark averaged more than $100 per barrel.West Texas Intermediate crude oil averaged $94.05 per barrel in 2012, down slightly from $94.88 in 2011. The annual average price gap between Brent and WTI reached $17.61 per barrel, up from the 2011 level of $16.38.The national weekly average pump prices for gasoline and diesel fuel during 2012 set record highs of $3.62 and $3.97 per gallon, respectively, and marked the second year in a row that the average price for either transportation fuel failed to drop below $3 per gallon during any week.

Natural Gas

Average, spot natural gas prices were lower compared to 2011, however both futures and spot prices increased in the latter half of the year.Natural gas prices were generally uniform across the country, except when residential and commercial demand peaked during the colder winter months. During these periods, pipeline constraints into the Northeastern United States led to increased separation of the average natural gas wholesale (spot) prices at major hubs in New England and New York above the average spot price at Henry Hub.

Electricity

Average, spot, on-peak wholesale electricity prices were lower across the United States and largely followed the trend in natural gas prices. Several short-term price spikes occurred during the summer months in several U.S. regions as electric demand increased to meet summer air-conditioning load.

See related article – Today in Energy, January 9, 2013


Coal

Wholesale (spot) coal prices across all basins fell during the first half of 2012, with steep declines in Powder River Basin (PRB) and Eastern basins, before stabilizing in the latter half of the year.Record exports of both thermal and metallurgical coal helped offset declines in consumption in the power sector.

See related article – Today in Energy, January 14, 2013


Natural Gas Liquids

Daily spot prices for natural gas liquids (NGL)–ethane, propane, normal butane, isobutane, and natural gasoline–were generally down in 2012. Ethane and propane, the lower-priced NGL, experienced the largest percentage declines relative to 2011 average prices. Prices for natural gasoline, isobutane, and normal butane more closely track oil prices.

A futures market is a trade center for quoting prices on contracts for the delivery of a specified quantity of a commodity at a specified time and place in the future. Futures markets reflect price expectations rather than current prices. The 'near-month contract' reflects the most immediate price expectation.

Energy and Water Spending Bill Proceeds with Deep Cuts for Renewables, ARPA-E

The fiscal year 2014 Energy and Water Appropriations Bill released by the U.S. House Appropriations Committee this week slashes $1.4 billion in funding to Department of Energy renewable energy and scientific research programs, including an 80% spending cut on the Advanced Research Projects Agency-Energy (ARPA-E) program.


The bill totals $30.4 billion—$2.9 billion less than the enacted fiscal year 2013 level, and $4.1 billion less than requested by the Obama administration. The legislation on Tuesday passed by a voice vote in subcommittee and will likely be voted on by the full House Appropriations Committee next week.


The cuts were achieved by targeted reductions to "lower-priority or unnecessary programs, including many within the DOE," lawmakers on the committee said. It slashes $911 million in funding (and provides $983 million) to renewable energy programs and reduces ARPA-E's funding by $215 million, an 81% cut compared to the enacted level for fiscal year 2013. The 2007-authorized program had been funded originally under the 2009 Stimulus Act.


However, it includes $450 million for research and development to advanced coal, natural gas, oil, and other fossil energy technologies, "which will help the country make greater use of our rich natural energy resources and help keep down energy costs," the committee's GOP majority said. Also included is $656 million for nuclear energy research and $25 million to support Yucca Mountain activities "to continue the viability of the program for the future." Lawmakers noted that the bill continues congressional efforts to roll back the Obama administration's "politically motivated" policy to scrap the permanent repository project in Nevada, which "runs contrary to the will of the Congress and the American people."


Significantly, the bill increases funding for nuclear programs—including $7.7 billion for weapons programs and $1.1 billion for nuclear reactors. It also provides $4.9 billion for national and regional infrastructure projects to help address navigation and flood control through the Army Corps of Engineers.


Committee Democrats blasted the cuts on renewables programs and ARPA-E as "deep and severe." Full committee Ranking Member Nita Lowey (D-N.Y.) lamented: “Our economy will be at a disadvantage to capitalize on the benefits of 21st century discoveries, ceding breakthroughs in areas like clean energy to China.”


Chairman Hal Rogers, however, defended the cuts saying, “In these tight budget times, sacrifices must be made to safeguard programs critical to the nation’s security and well-being. This bill reflects these hard choices, prioritizing funding to maintain our nuclear weapons and ensure the safety and readiness of the nation’s nuclear stockpile, and to invest in essential infrastructure projects to enhance safety and encourage commerce. This is a good bill that guarantees these programs are maintained, while recognizing current budget constraints,” he said.

Power Sector Laments Europe’s Uncertain Future Energy Policy

Energy policy in the European Union (EU) is in upheaval as concerns mount over the impact of energy costs on the competitiveness of the power industry. Over April and May, the EU voted on but failed to pass several crucial climate measures, from setting a renewables target for 2030 to boosting the carbon price of its floundering Emissions Trading System (ETS). Industry groups have said the policy uncertainty could prove expensive.


On May 22, EU leaders held the first of a special series of thematic discussions on economic sectorial and structural issues, but ensuing draft conclusions from that debate on how to limit the impact of energy costs seem to prioritize industrial competitiveness over climate change, calling on member states to ensure “competitive” energy prices and a diversification of energy supply. The conclusions also reportedly pledge to review the causes of Europe’s soaring energy prices by the end of the year. Separately, the European Commission in May reportedly drew up a draft action plan asking member states to consider removing or temporarily freezing taxes, including renewable and network levies, on energy-intensive industry for a period of two years.


Just a day before that summit (May 21), the European Parliament failed to set a renewables target for 2030 in the 40% to 45% range, approving instead a nonbinding resolution that says the EU should try to achieve a share of renewables in the overall energy mix of more than 30%. The bloc currently has three 2020 climate targets: an improvement of 20% on the continent’s carbon dioxide emissions, a 20% share of renewables, and a 20% improvement in energy efficiency.


And in April, by a 334–315 vote, European Parliament members rejected a proposed reform to reverse the sinking price of carbon and subsequent glut of permits in the ETS carbon trading program, Europe’s flagship climate policy that has seen a turnover that reached €90 billion in 2010. The proposed reform, also known as “backloading,” would have withheld 900 million carbon allowances and steepened an annual decline in allowance numbers to shore up carbon values. “We believe that backloading is now politically dead and it is very unlikely that any political intervention in the scheme will be agreed during the third phase [2013–2020],” said Stig Schjølset, head of EU Carbon Analysis at Thomson Reuters Point Carbon. “We do not envisage prices rising much above the current €3 mark and they may well drop lower at least until the end of the third phase. The focus will now shift towards structural, more long-term oriented measures but certainly this vote makes the EU ETS irrelevant as an emissions reduction tool for many years to come,” he said.


The events have prompted Europe’s electricity industry association EURELECTRIC, an entity whose members represent the power sector in 32 European countries, to decry current EU climate and energy policies as a source of “confusion, not clarity. Today’s policy framework is half European, yet still half national; half market-based, but also half command-and-control; and seems to be only half committed to the ETS,” says a May letter to EU heads of state from EURELECTRIC president and CEO of ENEL, Fulvio Conti.


Conti called on leaders to put an end to investor uncertainty and “urgently agree on a coherent top-down package of proposals which establish an ambitious, firm, long-term, economy-wide greenhouse gas reduction target for 2030 up to 2050, in line with the European Council goal.” It is imperative, he said, that the body work out the “regulatory disorder” not just to avoid windfall taxes and retroactive changes, but also to give investors a foundation through long-term policy. Without early investment signals, Europe could face a “lost decade” of climate and energy policy inaction between 2020 and 2030, and this would require a costly sprint to decarbonize in the last two decades before 2050, the group said, citing a report titled “Power Choices Reloaded” that it published in mid-May.


Among “serious” measures that should be tackled is an improved market design, including a European coordinated approach to capacity mechanisms in which “all assets contributing to the security of supply” are “fairly remunerated,” Conti and the heads of Gasterra, GDF Suez, Iberdrola, Eni, RWE, E.ON, and Gasnatural Fenosa urged in a separate release. Also required is a “more sustainable approach” to the promotion of renewables “so as to reduce costs to citizens and favour a greater convergence between member states.”


Siemens Energy, too, has voiced concerns about European energy policy direction. A study that the global power equipment and services company is conducting along with the Technical University of Munich to ascertain the utilization rate of resources of energy systems worldwide and how reliable that supply is suggests that billions are being wasted every year as a result of inefficiencies in worldwide systems and markets—and particularly in Europe’s. For example, “[i]f [renewables] installations were built at the sites in Europe that offer the highest power yields, some €45 billion of investment in renewables could be saved by 2030,” Siemens concludes (Figure 1).


1. More efficiently siting renewables. A study by Siemens Energy analyzing power-producing systems across Europe identifies considerable potential for optimization and concludes that if renewables installations were built at sites in Europe that offer the highest power yields (as shown in this image, which includes associated extension of the power grid), nearly €45 billion of investment could be saved by 2030. Several hurdles would need to be overcome, however, including implementation of a European Union–wide integrated electricity market. Courtesy: Siemens


But such a feat would require, among many other complex needs, a strongly centralized structure that could necessitate a single integrated energy market for Europe. In preparation for a presentation of the findings of Siemens’ study, and to offer possible solutions to future energy challenges at the World Energy Congress in South Korea this October, Michael Süß, CEO of Siemens’ Energy sector, has been engaging in a series of six roundtables with industry, policy-makers, and experts. The takeaway from the very first one in Brussels this May: Creating one European market is indeed an idealistic experiment, and its foremost challenge will lie in harmonizing 27 diverse European energy landscapes and creating political consensus among member states on how to proceed.


In another related development, ambitions to import solar power generated from North Africa to Europe, as initially proposed by the Desertec Industrial Initiative (Dii), have deflated. In late May, Dii CEO Paul van Son told EU media portal Euractiv.com that the initiative had abandoned “one-dimensional” thinking about the €400 billion plan to source 15% of Europe’s renewable power from the Maghreb by 2015. Dii is instead looking at a business model that creates integrated renewables markets.


Susanne Nies, head of Energy Policy and Generation at industry association EURELECTRIC, put it into better perspective. “Firstly, at a very basic level, we are still missing lines and capacities for export. Building these is technically difficult because of the deep waters in the Mediterranean,” she said. Beyond the link between North America and Europe, consideration should be given to how some countries, such as Spain, are already struggling with excess renewables capacity, and to cross-border interconnection lines, which are also congested.


“Secondly, it is difficult to argue that the EU needs the additional [renewable energy supply] capacity,” she pointed out. Renewables in Europe are already competing to replace existing conventional plants, and importing more renewable power would require “solving plenty of system issues,” a move that could require “giving time to the technical, economic, and regulatory framework to adjust.”


Finally, North Africa’s own power consumption is slated to grow tremendously, and it already exceeds demand, she said. “It would be a big mistake for Africa to neglect its own, indigenous power generation and risk its own security of supply for the sake of satisfying the demand of Europe.”


The 56-member Dii continues to have supporters—including RWE, E.ON, Deutsche Bank, ABB, and the German reinsurer Munich RE—even though it saw the high-profile withdrawal of Siemens and Bosch, and Spain’s reluctance to engage in deals given its current austerity measures.

Washington DC Government Agencies to be 100% Powered by Wind Energy

Washington D.C. has just announced a huge step forward in its quest to become America’s “greenest” city. The District of Columbia Department of General Services (DGS) has signed a one-year contract that requires all government agencies to use 100 percent wind power for their electricity needs. The new contract with Herndon-based Washington Gas Energy Services (WGES) improves upon the District’s prior commitment of using 50 percent wind-generated electricity.

The electricity flowing through each government agency building will be generated at WGES’ wind farm in Northern Virginia, Cleantechnica reports. According to WGES, switching to 100 percent wind power for electricity equates to taking 61,000 cars off the road for a year. Unfortunately, the current contract will be up next Spring. Renewable energy advocates hope that the District will choose to continue the arrangement after noting savings and emission-reduction.


As part of its recently announced Sustainable DC Plan, the city has established ambitious goals to increase use of renewable energy and reduce greenhouse gas emissions. Already, Washington, D.C. is one of the largest metropolitan areas for green economy jobs and is home to more than 200 LEED- and Energy Star-certified “green” buildings.


As part of its contract with WGES, the DGS will leverage its improved data acquisition program with services from Lucid Design Group and Honest Buildings. Lucid Design Group will deliver cloud-based dashboards for facility managers to identify – and fix – inefficiencies and anomalies in energy consumption, while Honest Buildings will provide a dynamic public interface for the public to see energy performance in DGS facilities.


“Going green helps foster economic growth and creates modern and vibrant communities across the District of Columbia,” said Brian J. Hanlon, Director, Department of General Services. “Our goals are to become more energy efficient and reduce our carbon emissions, and our strategic partnership with WGES is playing a role in helping us achieve these objectives.”
