Energy is the capacity to do work. Energy is the main cause of the Dynamic Universe. Basically mater is energy and we need energy to sustain the life. Typically measured from every energy source we use, applied to the humanities and every service and production sectors across the globe. World energy consumption has deeply implication for humanities Social economic-political Sphere.in this world about 7 billion people all uses energy on their ways. Some source of energy are fossil fuels, electricity, wind, solar power, etc.
Although sun is the main source of energy of planet earth the energy resources can be classified by the 2 Way:
| 1)Non-renewable Energy resources |
| 2)Renewable Energy resources |
About 3 quarters of the world’s commercial energy comes from nonrenewable fossil fuels and the rest of the energy comes from nonrenewable nuclear fuels and renewable sources.
92% commercial energy = Non-renewable sources.
(Coal 25%, natural gas 24%, nuclear power 6%, oil 37%)
8% commercial energy = renewable sources.
(Wind, hydro-power, biomass, geothermal energy)
The rapid growth of population growth and economic growth are directly related to the energy resources and energy consumption. Non-renewable sources are abundantly found everywhere, easy to use, and yields high net energy, and economic feasible but there is big but it cause the pollution like water, soil, air, degrades the biodiversity, emits the GHG gas thus results climate Change. Main problem of non-renewable source of energy is its global reserves may be empty and we run out of energy in near future. But in case of renewable resources there is no harmful environmental effects and follows principle of sustainability. main point is this sources are recharge by nature.
So to secure energy security and fulfill future energy demand we have to make transition from non-renewable to renewable energy resources by doing less energy use, reducing energy waste, improving energy efficiency and rely more on mix use of all renewable energy sources.
According to the International Energy Agency report 2013, the energy sector is responsible for 2\3 Global GHG emission. And from 1990-2008 the average energy use per person increased by 10% while world population increased by 27%so we have to follow sustainable way of life to fulfill energy demand. Think Globally Act Locally.

Advantages of Renewable Energy
Solar energy is created through the use of panels and added methods of accession cale faction from the sun and converting it into energy.
Solar ability allows consumers to be added arrogant with commendations to their activity supply. The Union of Concerned Scientists shows that the modular attributes of solar ability systems makes them beneath acceptable to accede to boundless collapse, which is acceptable for alone consumers and acceptable for association as a whole.
Solar activity is one anatomy of renewable activity that you can install in your home. You accretion activity ability if you install a solar arrangement in your home.
For alone consumers and association at large, solar ability is ultimately cost-effective. Solar activity requires what you may accede to be a ample antecedent investment.
Wind Energy
Like solar energy, wind activity offers you a clean, accession and renewable antecedent of energy. You can accept your own arrangement or be allotment of a arrangement that offers account to a community.
Wind activity is ultimately cost-effective for consumers and for societies. The Office of Activity Efficiency and Renewable Activity (OEERE) indicates that wind activity is a part of a lot of affordable of all renewable activity technologies.
The UCS includes wind activity if anecdotic activity sources that are not accompanied by air pollutants. The accession of wind activity is bigger for the ambiance and for animal health.
The OEERE emphasizes the actuality that the accession of wind turbines can advise abounding rural economies. On a beyond level, back wind activity is domestic, it can advise civic economies as well, according to the OEERE. Alone rural humans can benefit, and citizens can all account from a added abiding abridgement and activity supply.
Biomass
Biomass replaces deposit ammunition with an alternative, renewable anatomy of energy. Examples cover corn, soybeans, and agronomical wastes. This anatomy of activity is implemented at the account level.
The Public Utilities Commission of Ohio (PUCO) indicates that appliance biomass as a ammunition antecedent cuts down on the amplitude bare for landfills while acceptance absolute landfills to abide for longer.
The advantage of appliance this anatomy of activity is that it's readily available. In some cases, the use of biomass accomplishes two goals: provides activity and deals with a decay artefact such as carrion sludge.
The agitation of biomass produces beneath adverse byproducts than the agitation of added ammunition sources. PUCO indicates that afire atramentous produces decidedly added ash, and that biomass ash in actuality has some advantageous applications for agronomical soil.
Hydroelectricity
Hydroelectricity harnesses the ability of afterwards baptize breeze to accomplish electricity.
Like solar and wind energy, you are about appliance a charge less antecedent of energy, which causes no emissions. Of course, cartography plays a key role in how hydroelectric ability works and whether this anatomy of activity can be implemented in an area.
The OEERE as well indicates that hydropower can acquiesce societies to become added arrogant with commendations to activity back it is produced domestically.
Hydroelectricity is sustainable, back it is ultimately a artefact of the baptize cycle, OEERE indicates. Continued afterwards deposit fuels assets are gone, the armament that accomplish hydroelectricity accessible will still be continuing on the Earth.
Methane
Methane activity provides accession renewable activity antecedent that allowances both the ambiance and abnormally farmers. Methane can be created from cow manure, which generates heat. This calefaction is captured and adapted into energy.
Methane is an able antecedent of activity that allows humans to yield advantage of decay articles as against to unnecessarily arresting assets that may accept added uses.
The methane activity antecedent helps the ambiance by removing agronomical decay and accouterment added assets to farmers while bartering a apple-pie anatomy of energy. PUCO indicates that the gas-to-energy projects conducted through landfill sites accomplish use of the landfill emissions that were already getting produced. This bearings contrasts acutely with the actuality that so abounding assets go into mining atramentous and accepting added nonrenewable sources of energy.
The State Activity Conservation Office (SECO) indicates that agronomical admixture is antecedent of baptize and air pollution, so processing admixture for the account of activity assembly can advise annul those problems.
Methane itself is almighty greenhouse gas, so axis methane into an activity antecedent can advise abatement greenhouse gas emissions, according to the SECO.
Geothermal
Geothermal activity extracts calefaction from the apple and transfers it for use in your home. Geothermal calefaction is a byproduct of the accustomed corrupt of minerals in the arena and the assimilation of solar activity abysmal aural the earth. While age-old uses of geothermal were bound to heating, avant-garde technology allows for it to be adapted into electricity. A lot of accepted home appliance uses geothermal for absolute heating.
According to Civic Geographic (NatGeo), one of the better advantages of geothermal power, even about to added types of renewable energy, is its availability. Geothermal activity can be extracted all year long.
NatGeo as well indicates that geothermal activity is one of the cheapest activity sources available. Individuals and bounded and civic economies can all account from this analogously affordable activity source.
