That would be water. Water from rivers being very popular with the hydroelectric dams. Storing its potential energy behind the dam.
Lightning, solar energy, hydroelectric energy, geothermal energy, nuclear energy, and wind energy.
Wind, solar, and hydroelectric power. All kinds of renewable energy.
Hydroelectric power
Yes, hydroelectric could power a city. The issue with most green energy sources is cost and inability to obtain uninterrupted power on demand. Hydroelectric does not have these limitations. It does have some negative environmental impacts, just as all energy sources do.
The five sources of energy are solar, nuclear, wind, hydroelectric and fossil fuels. Nowadays there are five energy sources: fossil fuels, nuclear, wind, hydroelectric amd solar. The alternative sources are solar, wind and hydroelectric.
Wind Power, Geothermal Energy, Hydroelectric Energy
There are many ways in which energy can be obtained, some of these sources could be: Solar Wind hydroelectric solar agricultural geothermal tidal nuclear :)
There are many great energy sources other than wind turbines. There is hydroelectric power and solar power.
The energy sources that I am most excited about all have lower carbon emissions, compared to conventional energy sources. These include Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, and Hydroelectric Energy sources.
Solar Hydroelectric Wind Geothermal Biofuels
Water power and hydroelectric power.
The advantage of using solar, wind, and hydroelectric energy is that these energy sources are environmentally friendly, and they do not run out. The disadvantage is that they are generally more expensive to implement than traditional sources of energy like oil and gas.
