1.4. Energy Resources

Energy

It is the capacity of matter to perform work as the result of its motion or its position in relation to forces acting on it.
Energy associated with motion is known as kinetic energy, and energy related to position is called potential energy.
Example: a sw

Types of Energy Sources

The energy sources have been split into three categories:
Renewable sources
Fossil fuels / Non-renewable sources
Nuclear sources.

Renewable Energy

Renewable energy that comes from resources which are continually replenished such as sunlight, wind, rain, tides waves and geothermal heat.
New renewables such as, small hydro, modern biomass, wind, solar, geothermal and biofuels accounted for another 3%

Types of Renewable Energy Resources

1) wind
2) hydro
3) solar
4) biomass
5) biofuel
6) geothermal
7) LED energy

Wind Power

It is the energy contained in the force of the winds blowing across the earth's surface.
Airflows can be used to run wind turbines.
Wind energy can be converted into mechanical energy for performing work such as pumping water, grinding grain, and milling

Hydropower / Waterpower

It is the power derived from the fall of water from a higher to a lower level, and extracted by means of waterwheels or hydraulic turbines.
Waterpower is a natural resource, available wherever a sufficient volume of steady water flow exists.
Its developme

Solar Energy

It is the radiation produced by nuclear fusion reactions deep in theSun's core.
The Sun provides almost all the heat and light, Earth receives and therefore sustains every living being.
Solar energy applied energy from the sun in the form of solar radiati

Biomass

Biomass is biological material derived from living or recently living organisms.
In the context of biomass for energy this is often used to mean plant based material, but biomass can equally apply both animal and vegetable derived materials.
Biomass is ma

Biofuel

Biofuels include a wide range of fuels which are derived from biomass.
The term covers solid biomass, liquid fuels and various biogases.
Liquid Biofuels include bio alcohols, such as bioethanol and oils, such as biodiesel.
Gaseous Biofuels include biogas,

Geothermal Energy

Hot water and steam from underground can be used to drive turbines: this is called geothermal energy.
Several types of rock contain radioactive substances such as uranium.
Radioactive decay of these substances releases heat energy, which warms up the rock

LED Energy

Non-Renewable / Fossil Fuels

Burning coal, natural gas, and petroleum releases energy stored in the fuel as heat.
The energy contained by the fuels is derived from the energy of the sun.
The heat that is recovered upon combustion of the fuel can be used by us in several ways.
Combust

Coal

About 300 million years ago, enormous ferns and other prehistoric plants were common on the swamp-like earth.
When those plants died and fell to the ground, they were covered with water and they slowly decomposed.
As decomposition took place in the absenc

Natural Gas

Natural gas is almost always found in deposits of petroleum.
When the petroleum is drilled, natural gas is also recovered.
Wells with only natural gas also exist.
Once the natural gas is recovered, other fuels are extracted by processes called condensatio

Petroleum

Petroleum or "Crude Oil", is a liquid fuel that is present in various locations throughout the world.
It has many uses from the generation of electricity to the manufacture of medicines, plastics and other commercial items.
Much like coal, petroleum is fo

Why is renewable energy important?

Renewable energy still has a long way to go in order to replace fossil fuels and become primary source of energy consumption
-Positive environmental impact
greenhouse gas emissions decreased
-strong boost to economy in form of new jobs.
The number of peop

Energy Conservation

energy conservation refers to different methods and processes that have the main purpose in reducing the total amount of energy that is currently being used by industry, households and various other sectors of our society.

-important from th

Efficient Energy use / Energy Efficiency

Energy conservation refers to reducing energy through using less of an energy service.
Energy conservation differs from efficient energy use, which refers to using less energy for a constant service.
For example, driving less is an example of mileage vehi

Domestic Users- Energy Saving Guidelines

Switch off all unnecessary light save electricity, this our national duty.
Use energy savers instead of conventional bulbs and tube lights in order to reduce your electricity bill.
Adjust cooling of refrigerators according to the atmospheric conditions to

Industry - Energy Saving Guidelines

All industrialists must prepare energy plan and undertake energy audit.
Prevent leakages in order to save energy.
In order to save energy get the boilers turned after every three months.
All motors should be properly checked regularly.
Use energy savers,

Transport - Energy saving in vehicles

Get your vehicle properly tuned in order to reduce fuel consumption
Switch off the engine if the traffic signal is likely to remain red for a longer duration.
For travelling to the same destination use a sing vehicle instead of more, if possible. Opt for

Energy Conservation tips for Gas Consumers.

Minimize the use of heaters.
Turn on geyser only in the morning.
Repair gas leakages immediately
Switch off the stove after use

Electricity Consumers

With energy prices rising, it's important to make our home more fuel efficient. Use energy savers.
Change your light bulbs to fluorescent. They are bit more expensive to buy than standard light bulbs but much cheaper to operate.
Use lower wattage bulbs, e
