What is the best way to produce mega joules?

Question

With out using oil and nucluer power?

Answer 1

I think you are asking for mega watts, not joules.

Joules are a unit of energy, watts are a unit of power.

A MW is a lot of power, enough for as many as a thousands homes. But a large wind turbine will put out 3 MW or so, when the wind is blowing.

A large number of (expensive) solar panels will do that also.

You can also use solar concentrators to heat water to make steam to drive a steam turbine to drive a generator.

But the last 2 only work when the sun is shinning, and the wind turbine only when the wind is blowing. If you need steady power, then geothermal and ocean temperature difference generators are all that is left. And both require the right location.

But if you really want a MJ, then a small generator of some sort will do that, you just have to wait longer. Eg, a 1000 watt generator will generate 1 MJ in 1000 seconds. A 10 watt generator puts out 1 MJ in 28 hours.
