Solar energy is usually collected in either one of two ways:
-- Photovoltaic cells deliver electricity when the sun shines on them. If you
need mechanical energy, then you use the electricity to run a motor. You can
store the solar energy from the cells in batteries, so that you can run the motor
even when the sun is not shining.
-- Solar energy can be used to heat water. Really hot. Boiling even! You can
then blow the steam through the vanes of an electric turbine generator, giving
you electricity which, again, you can run motors with.
With a generator mounted on the "turbine". The propeller spins the generator shaft.
The definition of mechanical energy is energy in a mechanical form
No engine is 100% efficient: there is always some loss of energy between input and output.
All people use mechanical energy.
hey everyone this is jessica from mission tx..i hope you find the answer to this question cause i dont have it well got to go... .::BiROE&&FATAL::.
Yes
Yes.
how do we convert wind energy into mechanical energy
How do solar farms convert energy into electrical energy?
Pants can't convert solar energy...
no
solar cells are used to convert solar energy to electricity.
A motor convert electrical energy to mechanical energy.
There are two main ways to convert solar energy into other forms of energy. 1. Photovoltaic Conversion Photovoltaic cells, called solar panels, use the photovoltaic effect to convert sunlight into electricity. Photovoltaic cells in solar panels produce electricity by way of electron excitation caused by solar radiation. Both home and business applications frequently use this kind of energy conversion. 2. Thermal Conversion With the help of solar thermal systems, heat produced by the sun can be transformed into mechanical or electrical energy. Solar energy can be converted into mechanical, thermal, or electrical energy to suit a variety of energy needs in diverse industries.
Solar energy
Three types? I can think of more than that. But I suppose if we group some together: there is mechanical energy, solar energy, wind energy, hydro energy. Thermal energy in a power station is transformed into mechanical energy so is covered by that. But then both wind energy and hydro energy convert to mechanical before the electricity is produced. So really at a fundamental level there seems only mechanical and solar. Mechanical would include fossil fuels, (coal, oil, natural gas,), nuclear, wind, incinerators, hydro, geothermal, and biomass, which all drive a mechanical device to produce the electricity. Solar produces electricity directly from photovoltaic cells so that is not mechanical.
