The raw materials in Solar must be mined, transported and manufactured, some of those elements are toxic heavy metals. The real problem comes at the end of the life cycle, what happens to the hundreds of thousands of tonnes of material and how is that going to be recycled and reused. If just released into the environment, all of those toxic metals could end up in the ocean or our drinking water, possibly killing more people and causing more damage to the environment than other forms of electricity production. Wind turbines also have similar issues with the mining, killing of birds and bats and their recycling at the end of their life. There is a very large difference between clean energy and renewable energy which may not be as clean as we think.
