Renewable energy is generally defined as energy that is collected from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.
A clean energy revolution is taking place across America, underscored by the steady expansion of the U.S. renewable energy sector.
The clean energy industry generates hundreds of billions in economic activity, and is expected to continue to grow rapidly in the coming years. There is tremendous economic opportunity for the countries that invent, manufacture and export clean energy technologies.
Responsible development of all of America’s rich energy resources -- including solar, wind, geothermal, and water 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.
That day will come when we will be without coal and oil, however there are alternative sources of energy available to us which we are finally beginning to utilize more of. Fossil fuels are not good for the environment so to help protect our planet, it is wise for us to move forward with alternative energy for our future energy needs.
