The document describes hydrokinetic energy as a clean alternative to fossil fuels and traditional dams, utilizing the kinetic energy of moving water. It details various conversion technologies, including wave energy converters and rotating devices, while assessing the resource potential of US coastal and river systems. The text highlights the predictability of water-based power and the potential to avoid millions of metric tons of carbon dioxide emissions by 2025. However, it identifies significant barriers to commercialization, specifically citing a restrictive regulatory environment and the need for increased federal funding and streamlined permitting processes.

The Clean Air Task Force (CATF) argues that the MIT "Future of Coal" study relies on outdated data and ignores the commercial availability of carbon capture for IGCC plants. CATF contends that IGCC is a superior alternative to pulverized coal (PC) due to lower emissions of criteria pollutants and a significant cost advantage when 90% carbon capture is implemented. The document highlights that while PC carbon capture remains speculative, IGCC carbon capture is a "commercially proven process." CATF warns that following MIT's recommendation to build efficient PC plants today could lock in high global emissions, particularly in China, and instead advocates for banning new coal combustion plants in favor of rapidly commercializing advanced gasification and geologic storage.

Earthjustice blocked Florida Power & Light's proposal for a massive coal-fired power plant at the edge of the Florida Everglades in 2007. The Florida Public Service Commission rejected the project based on evidence regarding climate change, lack of energy conservation, and cost effectiveness. Consequently, Florida Power & Light invested $300 million in a 75 megawatt solar thermal facility, completed in 2010, which became the largest of its kind in the eastern United States.

The document summarizes key scientific literature on climate change, including the role of CO2 in temperature variation, ocean warming, sea level rise, and ecological impacts. It highlights foundational research from Svante Arrhenius and Charles Keeling, as well as reports from the IPCC and the Arctic Climate Impact Assessment. Key findings include the detection of human-induced ocean heat increases, the potential for significant sea level rise from ice sheet melt, and the correlation between rising tropical sea surface temperatures and increased hurricane destructiveness.

The document argues that shipping emissions are increasing at an alarming rate and that current IMO policies, such as voluntary indexing, are ineffective. It highlights the contribution of CO2, nitrogen oxides, and black carbon to climate change and Arctic melting, while warning that IMO inaction is prompting unilateral measures in the EU and US states like California and Washington. FOEI requests the IMO implement mandatory speed reductions, weather routing, and fuel economy standards, while insisting that these efforts remain separate from MARPOL Annex VI revisions regarding toxic air pollutants.

The document explains how wind energy integrates into the New England electricity grid to displace polluting fossil fuels, particularly natural gas, oil, and coal. It highlights the importance of siting turbines in high-wind areas to maximize pollution reduction and discusses policy mechanisms like cap-and-trade and renewable portfolio standards to accelerate the transition to clean energy.

The document advocates for wind power as a sustainable alternative to fossil fuels and nuclear energy, particularly in New England. It details the severe environmental and health costs of conventional energy—including CO2 emissions, air pollution, water consumption, and land degradation—while positioning wind energy as a low-impact solution with minimal land footprints and no operational emissions.

The document outlines the advantages of wind energy for New England, focusing on reducing dependence on imported fossil fuels, stabilizing energy costs, and generating local economic growth through taxes, lease payments, and jobs. It highlights specific projects in Massachusetts and Vermont to demonstrate positive community impact and environmental gains.

The document outlines the environmental and economic benefits of wind energy in New England, noting that over 60 percent of the region's electricity was generated from fossil fuels in 2005. It explains how wind power integrates into the grid via ISO New England to displace more expensive and polluting plants, particularly oil-fired plants during winter peaks. The text highlights that 18 proposed wind projects with a total capacity of 1,890 MW could avoid millions of tons of pollution annually, including over 3 million tons of CO2. It also discusses the importance of siting for efficiency and the role of policy mechanisms like cap-and-trade and renewable portfolio standards in accelerating the transition.

The document summarizes recent emissions inventories and health studies to demonstrate that shipping emissions are growing rapidly and significantly impacting human health. It highlights a global inventory projecting a 4.1% annual growth in emissions through 2040 and a North American inventory projecting 5.9% annual growth. The text argues that current and proposed IMO regulations are insufficient to offset this growth and calls for steep, fleet-wide reductions. Additionally, it cites California Air Resources Board (CARB) data showing that premature deaths attributed to ocean-going ships in California are predicted to more than double by 2020.

The Union of Concerned Scientists reports that ExxonMobil funded a network of ideological organizations to deceive the public about global warming. By spending approximately $16 million between 1998 and 2005, the company promoted a small group of contrarian scientists and used 'information laundering' through front groups to create a false impression of scientific debate. The report details how these tactics mirror the tobacco industry's historical efforts to hide the links between smoking and disease. Furthermore, the document outlines ExxonMobil's influence on the George W. Bush administration, including the appointment of climate negotiators and the censorship of government scientific reports.

The document establishes that limiting global warming to 2°C requires stabilizing atmospheric heat-trapping gases at or below 450 ppm CO2eq, which necessitates a global cumulative emissions budget of 1,700 GtCO2eq for 2000–2050. For the United States, this translates to a cumulative budget of 160 to 265 GtCO2eq, requiring emissions to be reduced by at least 80 percent below 2000 levels by 2050. The analysis finds that most federal legislative proposals fail to meet these targets, with only the Global Warming Pollution Reduction Act (S. 309) and the Safe Climate Act (H.R. 1590) remaining within the upper budget limit.

The document outlines Dr. James E. Hansen's testimony on climate change, highlighting that the United States is the largest source of CO2 emissions and that current 'Business-as-Usual' trends could lead to at least 5°C of warming by 2100. It warns of non-linear ice sheet disintegration in Greenland and West Antarctica, potentially causing sea level rises of 25±10 meters if warming reaches 2-3°C. Hansen argues that abrupt climate changes are practically certain under current emission trends, but an 'Alternative Scenario' could keep warming below 1°C if CO2 emissions are moderately reduced by mid-century and peak by 2100.

The World Resources Institute (WRI) reported 'net' CO2 emissions of 1,031 metric tons in 2004 and 978 metric tons in 2005, representing a 3% and 8% decrease respectively from its 2000 base year. To achieve its 'net zero' goal, WRI utilizes a combination of internal efficiency measures, the purchase of renewable energy certificates (RECs), and investments in GHG offsets through the Chicago Climate Exchange. The organization also updated its accounting methodology to exclude paper emissions from its primary goal due to calculation uncertainties, though it continues to track them separately. Beyond its own footprint, WRI manages several multi-stakeholder partnerships, including the GHG Protocol and Climate Northeast, to promote corporate greenhouse gas management.

Buildings account for 40% of total annual U.S. energy consumption and 48% of U.S. greenhouse gas emissions. The U.S. federal government operates over 500,000 buildings, which used 1.7 quads of energy in 2004, though the Federal Energy Management Program predicts a funding shortfall of over $2 billion for energy-efficiency projects. The document also highlights several high-performance buildings in the U.S. and Europe that achieved significant energy and water savings through sustainable technologies.

The report warns that California faces significant risks from global warming, with projected temperature increases between 3°F and 10.5°F by the end of the century. These changes threaten to severely reduce Sierra Nevada snowpack, increase the frequency of large wildfires, degrade air quality, and disrupt the state's $30 billion agriculture industry. The document emphasizes that while some changes are unavoidable, the most severe consequences can be avoided by reducing heat-trapping emissions to levels that keep warming within the lower range of 3 to 5.5°F.

The document reports a decline in US automotive fuel economy from a 1987 peak of 22.1 mpg to approximately 21 mpg in 2005, attributed to increased vehicle weight, horsepower, and the popularity of SUVs and light trucks. It details advanced technologies for efficiency gains, including aerodynamics, low-rolling-resistance tires, hybrid drivetrains, weight reduction, and direct-injection stratified charge (DISC) engines. Additionally, it highlights the impact of basic maintenance—such as tire pressure, air filter replacement, and engine tuning—on fuel economy, and notes that increased efficiency reduces foreign oil dependence and greenhouse gas emissions.

The document describes photovoltaic (PV) systems as semiconductor-based technology that converts sunlight into electricity. It highlights that PV is viable across most of the United States, with the potential for a 90-mile square station to meet the country's peak demand. Key benefits include the prevention of greenhouse gas emissions, the creation of high-technology jobs, and increased domestic energy security. While utility-scale costs range from $0.20 to $0.30 per kWh, the document notes that high upfront capital costs and intermittent power remain primary issues, though these can be mitigated by battery storage and utility-scale experimentation projects.

The Union of Concerned Scientists addresses several claims from Michael Crichton's State of Fear that cast doubt on global warming. The document explains that regional cooling trends are compatible with global warming due to factors like sulfate aerosols, and that the urban heat island effect is a minor component of temperature trends. It asserts that CO2 is a primary driver of warming, though other factors like volcanic eruptions influence short-term trends. The text highlights the retreat of major ice sheets and the long-term persistence of atmospheric CO2 as urgent reasons to reduce fossil fuel dependence.

The document details how NOAA officials, including lab director Dr. David Hofmann, attempted to restrict the use of terms like "climate change" and "Kyoto" in presentations and papers at the Seventh International Carbon Dioxide Conference. Evidence from FOIA requests and interviews suggests that funding agencies stipulated topics be limited to "carbon dioxide measurements and modeling, rather than climate change and climate modeling." Dr. Pieter Tans reported that material concerning climate change, including laboratory website content, required White House pre-approval, and that the conference website was ordered to remove links connecting CO2 increase to climate change. Dr. Tans noted that such restrictions damage the credibility of government scientists and create an atmosphere of intimidation for some researchers.
