This program demonstrates how renewable energy sources can be used to produce electricity with fewer environmental impacts. Scientists are making it possible to create electricity from renewable energy without producing carbon dioxide (CO2), the leading cause of global climate change. Students will learn how renewable energy is derived from natural resources that replenish themselves over a period of time without depleting the Earth’s resources. This program also explores some of the more recent innovations in solar, wind, and thermal energy. As scientists, engineers, and technicians work hard to make advances in renewable energy, an increasing number of consumers will come to adopt these emerging technologies, reducing reliance on non-renewable resources such as coal, oil, and natural gas that are expensive to extract and damaging to the environment. This program illustrates how renewable energy will help reduce the carbon footprint and potentially lower the effects of climate change. Renewable energy sources consist of two types: sustainable and naturally renewable. Sustainable sources include solar, wind, hydro, and thermal power. In Boulder, CO, 30% of power is currently coming from hydro power, while in Iceland, some 50% of heat and hot water is derived from geothermal sources. Taking advantage of the sun’s enormous energy, solar panels are now being set up over water in Europe and Japan, as are wind turbines. Apple’s CEO Tim Cook has invested in renewable energy, creating Energy LLC, which hopes to sell solar and wind power directly to consumers (one of the company’s solar projects consists of a large circular ring of solar panels). Naturally renewable sources of energy include biofuels that use plants and wood to produce fuels. The field offers many career opportunities, including materials scientists, environmental engineers, solar photovoltaic technicians and more.
