Hydroelectric.
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.
As energy is the main source of air pollution, pollution free sources of energy can help. Thus, solar, wind, and hydroelectric technologies can help.
yes it is pollution free
The energy in falling water can be captured by turbines and used to generate electricity. This is a renewable source of energy and is pollution free.
hydro electricity is an efficient source of energy 1. pollution free 2. renewable 3. no worries of exhaustion of natural resources
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.
Renewable electricity (made from renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel)) adds little or no pollution to the atmosphere. Nuclear fuel is also mostly pollution free (barring accidents, of course!).
Mostly advertising.
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.
