Document Summary
Projected to expel potential fossil fuels by 2300, so we need to consider what to do once we reach low fossil fuel levels. We should, however, start now, so technology can catch up to the demands. Total final energy use- oil (30), natural gas (22), coal (28), renewable energy (17) Renewable energy breakdown- traditio(cid:374)al (cid:271)io(cid:373)ass, (cid:271)iofuels, (cid:449)i(cid:374)d/solar/(cid:271)io(cid:373)ass , hydropower. In contrast to quantity, the quality of solar energy is low relative to fossil fuels. Power density combines two attributes of energy sources: the rate at. Intermittency which energy can be produced from the source and the geographic area covered by the source. Another quality difference between renewable fuels and fossil fuels is their energy density: the quantity of energy contained per unit mass of a fuel. The quantity/quality paradox of solar energy refers to the fact that the amount of solar energy intercepted each year by a square meter of the. Earth is small, thereby limiting its economic usefulness.
