Energy efficiency measures are thriving in state capitals around the United States, with several states – including Mississippi, Connecticut, Illinois, and West Virginia – taking major steps that moved them up the ranks in the seventh annual edition of the State Energy Efficiency Scorecard released by the American Council for an Energy-Efficient Economy (ACEEE).

For the first time in the history of the State Scorecard, the 2013 ranking of the states is being released with the participation of a U.S. Department of Energy secretary, Dr. Ernest Moniz, along with a top elected official of a state, Massachusetts Gov. Deval Patrick.

Available at http://aceee.org/state-policy/scorecard, the State Scorecard shows that the top 10 states for energy efficiency are: Massachusetts, California, New York, Oregon, Connecticut, Rhode Island, Vermont, Washington, Maryland, and Illinois. Massachusetts retains the top spot for the third year in a row based on its continued commitment to energy efficiency under its Green Communities Act.

In California, requirements for reductions in greenhouse gas (GHG) emissions have led it to identify several strategies for smart growth, keeping the state in a top position at No. 2. Connecticut is also closing the gap due to passage of a major energy bill in 2013, and Illinois is making its first appearance in the top 10 this year, reaping the benefits of increased energy savings called for in the state’s energy efficiency resource standard.

According to the 2013 State Scorecard, the five states most in need of improvement (starting with dead last) are: North Dakota; Wyoming; South Dakota; Alaska; and Mississippi. However, Mississippi also appears on ACEEE’s list of the top five most improved states, revealing an upward trend as more and more states embrace energy efficiency.

Last year Mississippi passed comprehensive energy legislation that included energy efficiency as a major component. The bill included provisions setting an energy code for commercial and state-owned buildings. Mississippi is now set to become a regional leader in energy efficiency. West Virginia’s score improved due to the state adopting stronger building codes. The other three most improved states in 2013 were Maine, Kansas, and Ohio.

“Energy efficiency is a critical tool for cutting harmful carbon emissions and the best way to reduce energy bills for America’s families,” U.S. Department of Energy Secretary Dr. Ernest Moniz said. “We applaud the continued progress in energy efficiency nationwide and stand ready to help states as they make their communities cleaner and more sustainable, while saving taxpayer dollars and fostering greater economic growth.”

“Massachusetts continues to lead the nation in energy efficiency because we have made the choice to shape our future, rather than leave it to chance,” Gov. Patrick said. “We will continue to focus on policies that create jobs, decrease dependence on imported energy sources and protect our environment by reducing emissions.”

“In every region we are seeing states embrace energy saving measures with growing enthusiasm,” ACEEE Executive Director Steve Nadel said. “From Massachusetts, which continues to be the pacesetter in the race to cut down energy waste, to Mississippi, which is emerging as a regional star; state governments are proving that smart policy can still cross partisan divides.”

“California continues earning its reputation as an energy leader by instituting the nation's most advanced energy efficiency standards for buildings and appliances, and for pushing the envelope on ratepayer-funded efficiency programs,” California Energy Commissioner Andrew McAllister said.

“Our standards alone have helped save ratepayers more than $75 billion since 1975, grown California's economy with local jobs, and protected our climate by reducing carbon emissions. ACEEE is providing a valuable service by recognizing energy efficiency leaders that other states can follow. We are proud to be one of the leaders.”

In the seventh edition of the State Scorecard, ACEEE ranks states on their energy efficiency policy and program efforts, and provides recommendations for ways that states can improve their energy efficiency performance in a variety of policy areas. The State Scorecard report serves as a benchmark for state efforts on energy efficiency policies and programs each year, encouraging states to strengthen their efficiency commitments as a pragmatic and effective strategy for promoting economic growth, securing environmental benefits, and increasing their communities’ resilience in the face of uncertain energy costs and supplies.

Other Findings

Facing uncertain economic times, states are continuing to use energy efficiency as a key strategy to generate cost-savings, promote technological innovation, and stimulate growth. The ACEEE Scorecard documents the following trends:

* Several states have made concentrated efforts related to energy efficiency. Arkansas, Indiana, and Pennsylvania continue to reap the benefits of their energy efficiency resource standards (EERS), leading to substantially greater electricity efficiency investments and savings compared to what ACEEE reported in the 2012 State Energy Efficiency Scorecard.

* A total of 20 states fell in the rankings in the 2013 State Scorecard report, due to both changes in the report’s methodology and substantive changes in their performance. Idaho fell the furthest, by nine spots, largely because it did not keep up with peer states in utility efficiency spending and savings. Wisconsin dropped six spots, due to a significant drop in energy savings realized by the state’s efficiency program.

* Connecticut passed a major energy bill in June 2013, calling for the benchmarking of state buildings, expanding combined heat and power programs, and doubling funding for energy efficiency programs.

* The leading states in utility-sector energy efficiency programs and policies are Massachusetts, Vermont, and Rhode Island. All three of these states have long records of success and continue to raise the bar on the delivery of cost-effective energy efficiency programs and policies.

* The leading states in building energy codes and compliance are California, Washington, and Rhode Island. During the past year, seven states adopted the latest iteration of building energy codes.

Methodology

The 2013 State Energy Efficiency Scorecard provides a broad assessment of policies and programs that improve energy efficiency in our homes, businesses, industries, and transportation systems. The State Scorecard examines the six policy areas in which states typically pursue energy efficiency: utility and “public benefits” programs and policies; transportation polices; building energy codes and compliance; combined heat and power policies; appliance and equipment standards; and state government-led initiatives around energy efficiency.

The American Council for an Energy-Efficient Economy acts as a catalyst to advance energy efficiency policies, programs, technologies, investments, and behaviors.

Carbon dioxide removal revenues worth £2bn a year by 2030

Engineered greenhouse gas removals will become "a major new infrastructure sector" in the coming decades says the UK's National Infrastructure Commission

Carbon dioxide removal revenues could reach £2bn a year by 2030 in the UK with costs per megatonne totalling up to £400 million, according to the National Infrastructure Commission

Engineered greenhouse gas removals will become "a major new infrastructure sector" in the coming decades - although costs are uncertain given removal technologies are in their infancy - and revenues could match that of the UK’s water sector by 2050. The Commission’s analysis suggests engineered removals technologies need to have capacity to remove five to ten megatonnes of carbon dioxide no later than 2030, and between 40 and 100 megatonnes by 2050.

The Commission states technologies fit into two categories: extracting carbon dioxide directly out of the air; and bioenergy with carbon capture technology – processing biomass to recapture carbon dioxide absorbed as the fuel grew. In both cases, the captured CO2 is then stored permanently out of the atmosphere, typically under the seabed.

The report sets out how the engineered removal and storage of carbon dioxide offers the most realistic way to mitigate the final slice of emissions expected to remain by the 2040s from sources that don’t currently have a decarbonisation solution, like aviation and agriculture. 

It stresses that the potential of these technologies is “not an excuse to delay necessary action elsewhere” and cannot replace efforts to reduce emissions from sectors like road transport or power, where removals would be a more expensive alternative.  

The critical role these technologies will play in meeting climate targets means government must rapidly kick start the sector so that it becomes viable by the 2030s, according to the report, which was commissioned by government in November 2020. 

Early movement by the UK to develop the expertise and capacity in greenhouse gas removal technologies could create a comparative advantage, with the prospect of other countries needing to procure the knowledge and skills the UK develops.

The Commission recommends that government should support the development of this new sector in the short term with policies that drive delivery of these technologies and create demand through obligations on polluting industries, which will over time enable a competitive market to develop. Robust independent regulation must also be put in place from the start to help build public and investor confidence.

While the burden of these costs could be shared by different parts of industries required to pay for removals or in part shared with government, the report acknowledges that, over the longer term, the aim should be to have polluting sectors pay for removals they need to reach carbon targets.

Polluting industries are likely to pass a proportion of the costs onto consumers. While those with bigger household expenditures will pay more than those on lower incomes, the report underlines that government will need to identify ways of protecting vulnerable consumers and to decide where in relevant industry supply chains the costs should fall.

Chair of the National Infrastructure Commission, Sir John Armitt, said taking steps to clean our air is something we’re going to have to get used to, just as we already manage our wastewater and household refuse. 

"While engineered removals will not be everyone’s favourite device in the toolkit, they are there for the hardest jobs. And in the overall project of mitigating our impact on the planet for the sake of generations to come, we need every tool we can find," he said.

“But to get close to having the sector operating where and when we need it to, the government needs to get ahead of the game now. The adaptive approach to market building we recommend will create the best environment for emerging technologies to develop quickly and show their worth, avoiding the need for government to pick winners. We know from the dramatic fall in the cost of renewables that this approach works and we must apply the lessons learned to this novel, but necessary, technology.” 

The Intergovernmental Panel on Climate Change and International Energy Agency estimate a global capacity for engineered removals of 2,000 to 16,000 megatonnes of carbon dioxide each year by 2050 will be needed in order to meet global reduction targets. 

Yesterday Summit Carbon Solutions received "a strategic investment" from John Deere to advance a major CCUS project (click here). The project will accelerate decarbonisation efforts across the agriculture industry by enabling the production of low carbon ethanol, resulting in the production of more sustainable food, feed, and fuel. Summit Carbon Solutions has partnered with 31 biorefineries across the Midwest United States to capture and permanently sequester their CO2 emissions.  

Cory Reed, President, Agriculture & Turf Division of John Deere, said: "Carbon neutral ethanol would have a positive impact on the environment and bolster the long-term sustainability of the agriculture industry. The work Summit Carbon Solutions is doing will be critical in delivering on these goals."

McKinsey highlights a number of CCUS methods which can drive CO2 to net zero:

  • Today’s leader: Enhanced oil recovery Among CO2 uses by industry, enhanced oil recovery leads the field. It accounts for around 90 percent of all CO2 usage today
  • Cementing in CO2 for the ages New processes could lock up CO2 permanently in concrete, “storing” CO2 in buildings, sidewalks, or anywhere else concrete is used
  • Carbon neutral fuel for jets Technically, CO2 could be used to create virtually any type of fuel. Through a chemical reaction, CO2 captured from industry can be combined with hydrogen to create synthetic gasoline, jet fuel, and diesel
  • Capturing CO2 from ambient air - anywhere Direct air capture (DAC) could push CO2 emissions into negative territory in a big way
  • The biomass-energy cycle: CO2 neutral or even negative Bioenergy with carbon capture and storage relies on nature to remove CO2 from the atmosphere for use elsewhere
