In this video from NOVA’s Energy Lab, learn about renewable energy sources and renewable energy technologies. A renewable source of energy is so plentiful that it can be considered limitless. Scientists and engineers are working on alternative energy technologies that make use of renewable energy sources (such as solar, geothermal, and tidal energy) and have less impact on the environment. The Sun is our greatest energy resource; solar technologies use its energy directly in the form of…
While we remain dangerously over-reliant on fossil-fuel power right now, it isn’t too late to make a change. If we take steps in the right direction we can beat our addiction. To safeguard the future, we must spark an energy revolution and if we do, we could end our fossil fuel addiction by 2050. This infographic shows how it could be done.
