Responsible development of all of America's rich energy resources -- including solar, wind, water, geothermal, bioenergy & nuclear -- will help ensure America's continued leadership in clean energy. Moving forward, the Energy Department will continue to drive strategic investments in the transition to a cleaner, domestic and more secure energy future.

Renewable energy is energy generated from natural resources-such as sunlight, wind, rain, tides and geothermal heat.

As science searches for new solutions to energy efficiency and renewable energy problems, this portal offers an easy access to Sigma-Aldrich materials and resources that may be useful in your research. Whether you work on alternative fuels, solar energy, energy storage or fuel cells, we are available to support your advanced technologies that neither deplete natural resources nor harm the environment.

To stay competitive, now more than ever, you need advisers who understand the industry. Eversheds Sutherland’s renewable and alternative energy lawyers work daily in the industry, so we recognize and understand the issues you are facing.

Renewable and Alternative Energy Sources The quest for energy independence, economic growth, and environmental sustainability increasingly suggests the importance of renewable energy sources. Renewable energy is gained by tapping into "existing flows of energy" and "natural processes" in ways that generate more usable energy than is expended in the production process.

Enter, alternative energy - any energy source that provides an alternative to the status quo. Renewable energy sources that don't produce carbon dioxide emissions and other greenhouse gasses that contribute to anthropogenic climate change. At altenergy.org we aim to cover solar, wind, biomass, hydroelectric power, geothermal and other carbon neutral energy sources that will help humanity transition to a sustainable future.

Renewable energy is sustainable as it is obtained from sources that are inexhaustible (unlike fossil fuels). Renewable energy sources include wind, solar, biomass, geothermal and hydro, all of which occur naturally. Renewable energy, generally speaking, is clean energy and non-polluting. Many forms do not emit any greenhouse gases or toxic waste in the process of producing electricity.

The consumption of biofuels and other nonhydroelectric renewable energy sources more than doubled from 2000 to 2016, mainly because of state and federal government mandates and incentives for renewable energy. The U.S. Energy Information Administration (EIA) projects that the use of renewable energy in the United States will continue to grow through 2040.
