Renewable energy is energy that comes from resources that renew themselves naturally. So many of the energy sources we rely on today are finite and stem from resources that will run out one day, so scientists are working to harness energy that is renewable. The most widely used renewable energy sources are solar power and wind power, and scientists consider them reliable resources for renewable energy because we always have sunlight and wind all over on earth. Other sources for developing renewable energy include geothermal heat, tides and waves, and biomass energy. Scientists throughout the world are working to develop renewable energy as an inexpensive and sustainable alternative to oil, gas, and coal. These renewable energy sources can help preserve a clean and healthy environment and save money for residential and business consumers.‎

Studying renewable energy can help you prepare for the future because of the positive environmental and economic impact that alternative sources of energy can have on the planet. The sources of energy that we use the most—fossil fuels—are finite, and they contribute to climate change because of the greenhouse gases that they emit. Renewable energy sources can contribute less to the pollution of the earth and can better serve the environment. Adding more sources of energy to the mix will also create competition in the marketplace, and increased competition tends to lower prices. When you study renewable sources of energy, you can contribute to a greener planet and a better economy for everyone.‎
