Renewable energy
Renewable energy is a
type of of energy which is gathered from renewable
resources such as wind, sunlight, water,
tides, geothermal heat these resources are called renewable energy
resources.
There are many forms
of renewable energy :-
1 1. Hydroelectric energy
2 2. Wind Power
3 3. Solar
energy
4 4. Biomass
5 5. Geothermal power
6 6. Hydrogen and fuel cells
1 1. Hydroelectric energy :- hydroelectric
energy is one of the renewable sources example Hydropower plants convert the energy of flowing water into
electricity. Currently Existing hydropower capacity is about 80,000 megawatts.
China is the largest hydroelectric energy producer.
2 2 . Wind energy :- in wind energy air flow
through wind turbines which passes through wind turbine to provide
mechanical power to move electric generator.The overall capacity of all wind
turbines installed worldwide is 52,552 magawatt.
3 3. Solar
energy :- in solar energy sunlight energy converted into electrical energy using photovoltaic
cells. China is leading the world in solar
power generation with 100 GW installation capacity.
4 4. Biomass :- The fuel consists
of organic matter such as industrial waste, agriculture waste and burn these
waste directly in specially designed power plants and used to replace up to 15% of coal as a fuel in
ordinary power plants. The largest use of biomass energy in Virginia is the
forest products industry.
5 5. Geothermal power :- Geothermal power
plants use high temperatures deep underground to produce steam, which then
powers turbines that produce electricity.
13.2 GW is the total installed
capacity in the world 2015.
6 6. Hydrogen and fuel cells :- fuel cell is an electrochemical device which
is same like a battery in that it converts the energy from a chemical reaction
directly into electricity and heat. Fuel cell technology has been around for
over 150 years.
Why
Do We Need Renewable Energy?
Here
is some points why we need renewable enrgyÃ
- Limited Fossil Fuels:-
Fossil fuels are limited they are finite
resources or you can say they are non renewable resources. Day by day human
population increases so rate of consumption of these fuels also increases, so this is why we need renewable
energy.
- Climate Change and Carbon Emissions :-
Many non renewable sources like coal,
natural gases, oil has greater tendency
to change climate and carbon emission as compare to renewable energy resources.
the changes we have seen to the climate in the last 100 years. Most of the
renewable resources are less carbon emission such as water, wind , tidal.
- Economical Stability
Energy produced from some renewable sources is
cheaper than that produced by non-renewable. So the energy prices in
case of renewable energy is quite stable, which help to keep the economic
stability.
- Energy Security
Energy security deals with possibility of
energy sources at an affordable price .it also treat with supply energy line
with economical development and environmental
needs. Price of fossils fuels are
increasing day by day because of more demand. Oil Prices fluctuated
badly last 10 years.
- Environmental Damage:-
Fossils fuels are harder to obtain, transporting fuels
from the mine causes air pollution when fuels are burned they emit some
dangerous toxin which help to increase global warming.
- Public Health:-
Fossils fuels gas, oil , coal mining and
drilling create higher level of pollution which affect the local environment .
Public health is affected by these non renewable sources.

ReplyDeleteClimate change is real. We are electricians in Pasadena and we strive to use sustainable energy. LED lighting is an example. You can call any electrician near me and ask about how they can help you with that.
