In this video clip from Earth: The Operators' Manual, host Richard Alley discusses China's efforts to develop clean energy technologies and to reduce CO2 in the atmosphere, by building coal plants using CO2 sequestration technology. (scroll down page for video)
This video provides an introduction to benefits and limitations of many sources of energy including fossil fuels, nuclear, hydro, wind, solar, geothermal, and biomass. It also discusses hydrogen and hybrid cars.
In this activity, students will determine the environmental effects of existing cars and a fleet consisting of their dream cars. They compute how many tons of heat-trapping gases are produced each year, how much it costs to fuel the cars, and related information. Then, students research and prepare a report about greener transportation choices.
U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2008
May 31, 2011
The U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2008 (USDA GHG Inventory) is a comprehensive assessment of greenhouse gas emissions and sinks in U.S. agriculture and forests. The USDA GHG Inventory provides extensive, in-depth emissions and sinks estimates for livestock, cropland, and forests as well as energy consumption in livestock and cropland agriculture.
Special Report on Renewable Energy Sources and Climate Change Mitigation
April 30, 2011
The Special Report on Renewable Energy Sources and Climate Change Mitigation, released by the Intergovernmental Panel on Climate Change in May 2011, assesses existing literature on the future potential of renewable energy for the mitigation of climate change. It covers the six most important renewable energy technologies, as well as their integration into present and future energy systems.
Building America: Resources for Energy-Efficient Homes
November 30, 2010
A series of publications by the Department of Energy's Office of Energy Efficiency and Renewable Energy to help residential builders achieve whole-house energy savings in five major climate zones.The series includes best practices and case studies for new and retrofitted projects.
Greenhouse gas emissions and increased global temperature will change weather, climate, ecosystems, and food supply. Each degree Celsius (1.8 deg Fahrenheit) increase in global average temperature (up to 4 deg C) would likely result in the following: 5% to 10% less total rain in southwest North America, the Mediterranean, and southern Africa; 5% to 10% less streamflow in some river basins; 5% to 15% lower yields of some crops. The document clarifies short- and long-term consequences of various scenarios.
Transportation's Role in Reducing U.S. Greenhouse Gas Emissions
March 31, 2010
This U.S. Department of Transportation report, submitted to the U.S. Congress in April 2010, evaluates a range of strategies for reducing greenhouse gases from transportation including: introducing low-carbon fuels; increasing vehicle fuel economy; improving transportation system efficiency; aligning transportation planning and investments to achieve GHG reduction objectives; and pricing carbon.
Assessing Economic Impacts of Greenhouse Gas Mitigation
May 14, 2009
Reliable estimates of the costs and benefits to the U.S. economy for various emissions reduction and adaptation strategies are critical to federal climate change R&D portfolio planning and investment decisions. At the request of the U.S. Department of Energy, the National Academies organized a workshop to consider these issues. The workshop participants discussed three dimensions: policy, analysis, and economics.
