The document highlights the inefficiency of the United States' building stock, which consumes 42 percent of the nation's total energy, and promotes five strategic solutions—technology adoption, integrative design, policy updates, low-cost financing, and valuing non-energy benefits—to achieve deep energy retrofits and support a cleaner electricity grid.

The Rocky Mountain Institute contends that the U.S. government has historically provided far more subsidies to fossil fuels than to renewables, citing $72 billion for fossil fuels versus $29 billion for renewables between 2002 and 2008. The document argues that wind and solar are rapidly becoming cost-competitive, noting a 43% decline in solar PV installed costs from 1998 to 2010. It further highlights the economic burden of fossil fuel externalities, estimated at $63 billion annually, and dismisses the Keystone XL pipeline as a viable energy security solution because it does not support the electricity system.

Amory Lovins defends the U.S. military's adoption of renewable energy and biofuels against criticisms from RADM Robert G. James. Lovins asserts that reducing oil dependence is a strategic necessity to protect service members from convoy attacks and improve combat effectiveness. He clarifies that his research advocates for biofuels derived from waste and non-food crops rather than food crops, and highlights the development of ultra-efficient carbon-fiber vehicles as a means to reduce oil reliance.

The U.S. Department of Defense (DoD) is implementing a wide range of energy efficiency and renewable energy strategies across the Army, Navy, Marine Corps, and Air Force. These initiatives aim to reduce greenhouse gas emissions, lower long-term costs, and enhance mission effectiveness by decreasing dependence on liquid fossil fuels. Key goals include achieving 'net-zero' energy for numerous installations by 2020 and 2030, increasing the use of alternative fuel blends for aviation and naval vessels, and deploying diverse renewable technologies—such as solar, wind, geothermal, and biomass—at domestic and overseas bases. The DoD's efforts are guided by internal strategies, a 2010 Memorandum of Understanding with the Department of Energy, and federal mandates including Executive Orders 13423 and 13514.

The report analyzes the potential for the Midwest to transition to a clean energy economy by adopting the Midwestern Governors Association's (MGA) targets: reducing electricity use by 2% annually and sourcing 30% of electricity from renewables by 2030. Using a modified National Energy Modeling System (NEMS), the Union of Concerned Scientists finds that these goals are achievable and would lead to significant job creation, consumer savings, and carbon emission reductions. The analysis highlights wind and biopower as the most competitive resources, while noting that transmission capacity remains a primary barrier. The report argues that regional targets would complement a federal carbon policy, making such a policy more affordable for consumers.

The report outlines a pathway for Seattle to reach net zero greenhouse gas emissions by 2050. By implementing aggressive strategies across transportation, buildings, and waste, the city could reduce per capita core emissions by 91% relative to 2008 levels. Key drivers include a massive shift toward electric vehicles, deep energy efficiency retrofits in the built environment, and a transition to low-carbon energy sources like biomass-fired district energy. While the scenario achieves a 90% reduction in core emissions, the report notes that the final 10% may require offsets or sequestration.

The document outlines China's shift toward energy efficiency and non-fossil fuel development, driven by energy security, environmental protection, and economic restructuring. It details the targets of the 12th Five-Year Plan (2011-2015), including carbon and energy intensity reductions. The author highlights China's rapid expansion in wind, solar, and high-speed rail, while noting the strategic importance of carbon capture and storage. Finally, it argues that China's clear policy framework creates significant investment opportunities for U.S. companies in clean technology.

The document examines the strategic importance of low-carbon technology for the EU, highlighting the risk of 'high carbon lock-in' if infrastructure decisions today commit economies to high-emissions pathways for 20-30 years. It argues that the current 20% emissions target is insufficient to drive the necessary scale and speed of innovation. The authors propose a 30% target by 2020 to provide certainty for investors and spur the deployment of technologies like electric vehicles and carbon capture and sequestration (CCS). The report also emphasizes the need for a system-wide risk management approach and increased international cooperation, particularly with China, the US, and Japan, to create integrated global markets and avoid protectionism.

The report argues that the EU's current Climate and Energy Package is insufficient to reach its 2050 goal of 80-95% emissions reduction at a reasonable cost. It suggests that moving to a 30% reduction target by 2020, combined with proactive investment policies in the building and transport sectors and a more predictable carbon price signal via the ETS, would reduce long-term costs and prevent the EU from losing market share in low-carbon technologies to competitors like China and South Korea.

The document finds that Estonian transport trends are unsustainable, characterized by rapid increases in private car use and road freight, leading to transport fuel use per unit of GDP that is twice the EU average. It argues that current policies are insufficient to meet EU greenhouse gas (GHG) emission limits for 2020 and proposes a combined approach of technical vehicle efficiency improvements and modal shifts to achieve sustainability.

The Union of Concerned Scientists' 2010 Automaker Rankings evaluate eight major car companies using government data from model year 2008. Honda is ranked as the greenest automaker, while Chrysler is identified as the most polluting for the fourth time in ten years. The assessment emphasizes that overall environmental performance depends on cleaning up entire fleets, including high-volume sellers, rather than relying on a few niche green models.

The policy brief proposes a 'feebate' system—where inefficient vehicles are surcharged and efficient ones are rebated—to overcome consumer discounting of long-term fuel savings. It outlines design recommendations from an RMI-hosted expert forum, including size-neutrality and manufacturer-level implementation. The brief cites France's 'bonus-malus' program as a successful example that significantly reduced new vehicle CO2 emissions, while noting that a U.S. version should prioritize technological innovation across all vehicle sizes rather than just shifting buyers to smaller cars.

The letter advocates for a national programme of energy efficiency and a reduction in overall energy demand to improve energy security. It calls for an increase in the 2020 renewable energy target, a tenfold increase in renewable R&D funding—potentially funded by military budget cuts—and the implementation of a Renewable Heat Incentive. The authors argue against new nuclear build, insisting the industry pay full costs for waste management and insurance without public subsidies, and suggest delaying construction decisions until safety and waste assessments are complete.

The document asserts that biofuel production and transport lead to dangerous spills, leaks, and fires that pollute ecosystems and kill aquatic life. It highlights specific incidents in Missouri and Iowa and notes that cleanup procedures for water-soluble fuels like ethanol are underdeveloped. The text advocates for shifting taxpayer funding from corn ethanol toward energy conservation, public transportation, electric cars, and sustainable solar and wind technologies.

The report challenges the traditional utility assumption that 'baseload' power plants are necessary for grid stability, noting that all generators, including coal and nuclear, experience outages. It proposes a new electricity paradigm integrating energy efficiency, demand response, renewables, and storage. The authors assert that variable renewables like wind and solar can reliably meet demand if utilities use existing plants differently, incorporate new storage technologies, and increase control over demand. Examples from Denmark, Germany, and a NREL study on the eastern U.S. are cited to demonstrate the feasibility of high renewable penetration.

The report finds that Estonia's transport system is not developing sustainably, with car use and road freight growing in tandem with the economy, leading to high energy intensity and greenhouse gas emissions. While traffic fatalities have decreased significantly, urban air quality has suffered due to increased particulate matter from cars. The report compares Estonia's performance with EU averages and neighbors (Finland and Latvia), noting that Estonia has some of the least fuel-efficient new cars in Europe. Three scenarios for 2020 are analyzed: a 'BAAS' (baseline) scenario where trends continue, a 'TEHNO' scenario focusing on rapid vehicle efficiency gains, and an 'EFEKT' scenario focusing on mobility management and sustainable transport modes. The authors recommend a combination of both TEHNO and EFEKT measures, including CO2-based vehicle taxation, improved public transport and active mobility infrastructure, and integrated urban planning to decouple economic growth from transport demand.

The study demonstrates that the EU can achieve domestic emission cuts of 40% by 2020 and 90% by 2050 through radical energy efficiency, a shift to renewables, and the phase-out of fossil fuels and nuclear power. It argues that such a transition is technically possible and economically bearable, costing approximately 2% of the EU's cumulative discounted GDP between 2010 and 2020. To achieve climate justice, the report asserts the EU must also provide between €150 billion and €450 billion annually by 2020 to support mitigation in developing countries.

Friends of the Earth criticizes Chrysler for scrapping its plans to produce large volumes of electric vehicles after receiving $15.3 billion in government bailout funds. The organization notes that Chrysler's revised sales targets for 2014 are significantly lower than the 500,000 vehicles promised by 2013, potentially leading to over one million extra tons of annual carbon dioxide emissions starting in 2014.

The report argues that China can achieve a deep carbon reduction by 2050 through sectoral transformations in electricity, industry, transport, and buildings, provided it receives international financial and technological support. It proposes a combination of domestic carbon taxes, a future cap-and-trade system, and a new 'Inter-country Joint Mitigation Plan' to facilitate technology transfer. The analysis emphasizes that a low-carbon transition is essential for China's modernization, offering opportunities to move up the value chain and improve energy security, though it will require active labour market policies to manage job losses in heavy industry.

The report presents a mitigation scenario for the EU27 to reduce greenhouse gas emissions by 40% in 2020 and 90% by 2050 relative to 1990 levels. This is achieved through radical energy efficiency, a shift to renewables, and the phase-out of fossil fuels, nuclear power, and carbon capture and storage. The analysis also estimates that Europe's fair share of international climate finance for developing nations would range between €150 billion and €450 billion by 2020.
