Which resources are renewable?

Answer 1

Renewable means that the thing can renew itself by growing quickly, like plantation pine trees, or grass, or crops, or chickens. Or it can renew itself by being part of a cycle, like water, which usually comes back as rain. Or it can renew itself like the power of the sun, or the wind, or the tides, which always come back afresh, even if we have used as much as we can of it today to harness electricity.
