Solar power plant
All energy resources are pollution free. It is extracting some of the energy from those resources that causes pollution. Extracting energy, by any means, from any resource, will cause pollutions of some kind somewhere in that cycle. There is no way to extract energy from anything without doing so in some way.
yes it is pollution free
Resource pollution means contaminating a given resource. Contamination of water can be considered as a good example of resource pollution.
In hydro power or solar power the energy source is pollution free but the process of manufacturing and building the plant is not of course.
Hydroelectric.
yes, because it is a renewable resource it is free
Renewable energy can't run out. Non-renewable energy WILL run out. Renewable energy is produced at a constant rate, non-renewable is not. Renewable energy is free when the generator is built, non-renewable is not. Renewable energy does not cause pollution (with the exception of biofuels), non-renewable energy does.
One of the first energy sources was fore- from wood and coal- but it creates a great deal of air pollution ans is not used very often anymore in developed countries.
As energy is the main source of air pollution, pollution free sources of energy can help. Thus, solar, wind, and hydroelectric technologies can help.
After the initial set costs, solar energy on paper is "free" energy, it is very low maintenance and pollution free
Actually solar energy systems do generate pollution, but the vast majority of that pollution is generated during manufacture not use. This makes containing and limiting the pollution much easier. After approximately 3 months of use, the renewable energy produced by the panels has compensated for the initial pollution. Then the panels produce free, clean, renewable energy with no carbon dioxide pollution.
Geothermal energy is good because it is a form of green energy. That means it is pollution free and does not harm the Earth. In fact, geothermal energy can prevent pollution and take away pollution as it can use greenhouse gases, which is one of the major killers of our planet.
