Sources of Energy An Overview

Sources of Energy The Sun – Ultimate source of much of our energy – Most non-renewable energy sources are means of storing solar energy – Solar, wind, and biomass

Sources of Energy The Moon – Tidal/Wave Power – Works with sun and the rotation of earth Gravity – Hydro power

Sources of Energy Nuclear – Fission – Fusion – The Sun – Geothermal

Non-Renewable Energy Energy derived from sources which are not replaced or are replaced at a rate slower then it is consumed.

Renewable Energy Energy derived from sources which are replaced as fast as they are consumed or are so plentiful that they are for all practical purposes infinite.
