The Earth is running out of our non-renewable energy sources and we need to start investing in renewable sources. My top two-energy source would have to be hydropower and solar power. Both are renewable and are in great abundance on this planet. Humans are using too many types of fossil fuels and are slowly but surely killing our planet. The switch may not be easy for all involved but will benefit us in the long run. I think that countries should encourage more people to switch to renewable energy sources because people don't want to change.
Did you know that the sun would produce enough energy on to the earth in one day to power the entire planet and its needs for an entire year. Also if we covered a small portion of the Sahara desert with solar cells we would meet all the world’s energy needs.
As long as the sun is still shining we will have an unstoppable source of energy.
Hydropower is also a great source of energy; some turbines can achieve efficiency of 95 % and more. Hydropower has some great benefits but also has a few slight problems. Since it relies on rivers and water currents it, may disturb ecosystems in the water, but apart fro that is a great source fro our planet.
Renewable sources are the way of the future and unless we switch to them soon we will have polluted to much to change.
