how about what others say
that energy is wasted when used
and can't be renewed.
that's in physics right?
can you give any connections to that?

Continually renewed, the same should be said for hydro. They are an important part of our global energy balance:

as one example of how the energy earth receives from the sun gets used.

Solar and wind power are renewable sources of energy. Using them does not deplete them. Things like oil are non-renewable, there is a finite amount available, when they are used up there is no more.

solar: Its free 'after' you pay for a 20,000$ piece of panel and then you have matenince. Then what do you do when it rains? wind: Its a GIANT SPINNING BLADE!!! So sometimes birds die. About 4000 a year world wide. hydrogen: Clean fuel in, drinkable waste out. lithium: The lithum battery life has ben multiplied x10. So yay. At the rate the world uses it, gas will be depleted in 100 years. However cheap gas prolly won't last anothr week. But we can now turn turkys into thir weight in oil in 1 week with some time travel doo-hicky.

Renewable.
Only fossil fuels and nuclear energy are classed as non-renewable.
Wind and solar energy is constantly being replaced (renewed) by the action of the Sun on our atmosphere but fossil and nuclear fuels need millions of years to produce.

Renewable, the theory being that wind and the sun are endless, they will never expire or run out.

They are renewable, at least until the sun burns out.

Renewable.

The sun and wind are not things that, once used, will take millions of years to replace (such as coal or petroleum.)
