Wind solar

Wind and solar. Some facts that proponents fail to mention and probably are not aware. Need lots of land. It takes 3 million solar panels to equal an average power plant and that would take 3,000 acres vs a power plant using up ten acres. Must have back up energy source for when the wind doesn't blow and the sun doesn't shine. On average the sun shines 12 hours per day but solar panels are only efficient for about 6 hours. Wind mills work about 25% of the time. To add to the inefficiency are the many miles of transmission towers needed to get the power to where it is needed. Solar panels receive subsidies but only the wealthy can afford to install them. Even those with panels only use them for electricity and they keep their natural gas for back up and heating. Wind and solar require the mining of and disposal of materials which are damaging to the earth. One interesting thing about wind and solar. You can search the Internet asking about the downside to wind and solar and you will get the start up cost, the need for a back up and the space but there is no mention of the harm caused to the environment by mining and disposing of the elements needed to make wind mills and solar panels. Why is that. The people who write these articles have a vested interest in wind and solar. Politicians who get kick back, manufacturers of windmills and solar panels and pro green writers who get grant money from green companies.
