Transcript of Energy Resources

Energy Resources Energy Energy Resources Renewable Energy
Resources Non-renewable Energy
Resources Fossil Fuels Nuclear Power -In general, energy is the strength &
vitality required for sustained physical or
mental activity.

-In physics, energy is an observed
quantity that is understood as the ability
of a physical system to do work on
other physical systems. -Energy resources are basically
anything that can be used as a source
of energy.

-There are 2 types of energy
resources: 1) Renewable
2) Non-renewable -Renewable energy is energy that
comes from natural resources.

-They are renewable because they are
naturally replenished at a constant
rate. -A non-renewable resource is a natural resource which cannot be reproduced, grown, generated, or used on a scale which can sustain its consumption rate, once depleted there is no more available for future needs.

-Also considered non-renewable are resources that are consumed much faster than nature can create them. -Fossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms.

-Fossil fuels contain high percentages of carbon and include coal, petroleum,oil, and natural gas.

-Fossil fuels are non-renewable resources because they take millions of years to form, and reserves are being depleted much faster than new ones are being made. -Nuclear power is the use of sustained nuclear fission to generate heat and electricity.

-It's non-renewable because it relies on fresh supply of uranium being found and extracted from ores which is finite, and there is no way to replace this once it is used up. Hydropower -Hydropower or hydroelectric power comes from using water to make electricity.

-Water cycles from ocean evaporation to cloud formation to rain & snow precipitation to runoff back into the ocean. Since this cycle & its energy is a continuous loop, hydropower can produce renewable energy. Biomass -Biomass energy is energy produced by burning biomass. Biomass is material encompassing all the living matter in an area.

-Biomass can be converted into energy-providing biofuels, such as biogas, methane, methanol & ethanol. Geothermal -Geothermal energy is thermal energy generated and stored in the Earth.

-Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface.

-Down even deeper to the extremely high temperatures of molten rock called magma. Wind -Wind energy is energy that is created by using the wind to generate power.

-It's a form of kinetic energy that can be transformed mechanical energy or electricity.

-Wind power is created by different types of wind power generators. The 2 most commonly used ones are: 1) Windmills
2) Wind Turbines Solar - Solar energy is energy derived from the sun; it's the sun 's ability to convert sunlight to electricity.

-Solar energy comes in 2 main forms: 1) Thermal
2) Electric

-Thermal: sun's ability to provide elevated forms of heat.
E.x. Swimming pools, washing machines
-Electric: energy used to make electricity directly from the sun.
E.x. Calculators, Watches THANK
