Solar power plays a very large part in reducing emissions and fighting global warming. There are also other forms of energy that are very important as well. However, solar energy is a very important part of it because the sun is available pretty much everywhere. It is a great way to get pollution free power.
No, solar energy is not the key to reducing emissions and fighting global warming. While it is a step in the right direction, as it stands alone it cannot solve the problem. Human beings are going to have to stop producing such large amounts of waste. This in combination with such solutions as solar energy will be the key to fighting global warming.
