What is the source of solar energy?
Solar power is energy from the sun that is converted into thermal or electrical energy. Solar energy is the cleanest and most abundant renewable energy source available, and the U.S. has some of the richest solar resources in the world.
Is living near a solar farm Dangerous?
All doping agents used in the manufacturing of solar panels are toxic to carbon based life forms, the most popular of these being cadmium telluride. Cadmium telluride has specific chemical properties that make it especially hazardous to all life forms residing near solar power plants.
Why Solar is bad?
New research shows, albeit unintentional, that generating electricity with solar panels can also be a very bad idea. In some cases, producing electricity by solar panels releases more greenhouse gases than producing electricity by gas or even coal.
What are the negative effects of solar energy?
Land Use. Large utility-scale solar panels take up a lot of space, which can result in environmental degradation and habitat loss. Solar farms that cover a large amount of land are likely to have an impact on the local fauna and flora, particularly on birds.
