Wind energy is not called solar energy. Solar energy is the energy from the sun, while wind energy is just wind energy.
Solar (Light), Wind and Hydro (Water)
Solar energy would be the cheapest to maintain but installation costs are high. Wind energy would be free when the wind blows, but again would cost a lot to install. There are many variables that go into what makes energy sources the pricing that they are.
solar ,wind , oil and water
1. solar energy you get from the sun while wind energy you get from the wind 2. solar energy you have to have solar things (ex solar ovens) wind energy you need a windmill for.
solar energy is energy from the sun and wind energy is energy from the wind
alternative fuels
Wind and solar are renewable energy.
Renewable energy is solar, wind, water and thermal power. Solar energy radiates from the sun.
