This document summarizes different types of energy resources, dividing them into two main groups: renewable and non-renewable. Renewable resources, such as solar, wind, and hydropower, come from sources that replenish naturally within human timescales, while non-renewable resources like coal, petroleum, and natural gas form over long geological periods and do not renew themselves rapidly enough to be considered renewable or sustainable. The document provides brief descriptions of various energy sources including geothermal, solar, wind, hydropower, biomass, petroleum, natural gas, coal, and nuclear energy.
2. Energy resources
•Two important groups:
RENEWABL
E
Comes from resources
which are naturally…
on a human timescale.
NON
RENEWABLE
Resources that don’t
renew itself at a
sufficient rate
3. Geothermal energy
•Thermal energy
•Generated and
stored in the Earth

4. Solar energy
•Radiant light and
heat from the sun
•Harnessed
•Technologies

9. Gas energy
It is a fossil
fuel
Layers of buried
plants and
animals
Expose to intense
heat and pressure
over mountains of
years
10. Nuclear energy
•Use of
sustained
nuclear fission
•Generate
heat and
electricity
