RENEWABLE ENERGY RESOURSES

Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat.

AREAS WHERE WE USE R.E.R.

POWER GENERATION

HEATING

TRANSPORT FUEL etc.

MAINSTREAM RENEWABLE TECHNOLOGIES

1. WIND POWER

2. HYDROPOWER

3.SOLAR POWER

4.BIOMASS

5.BIOFUEL

6.GEOTHERMAL ENERGY

WIND POWER In this technology airflow is used to run turbines also called wind turbine by which

power produces.

Modern utility scale wind turbines ranges from around 600kw to 5MW of rated power , although turbines with rated output of1.5-3MW are commonly in use today.

Globally, the long-term technical potential of wind energy is believed to be five times total current global energy production, or 40 times current electricity demand, assuming all practical barriers needed were overcome.

The Shepherds Flat Wind Farm is a 845 megawatt (MW) wind farm in the U.S. state of Oregon.

HYDROPOWER

Energy in water can be harnessed and used. Since water is about 800 times denser than air, even a slow flowing stream of water, or moderate sea swell, can yield considerable amounts of energy.

Micro hydro systems are hydroelectric power installations that typically produce up to 100 kW of power. They are often used in water rich areas as a remote-area power supply(RAPS).

The largest of which is the Three Gorges Dam in China and a smaller example is the Akosombo Dam in Ghana.

Hydropower is produced in 150 countries, with the Asia-Pacific region generating 32 percent of global hydropower in 2010.

China is the largest hydroelectricity producer, with 721 terawatt-hours of production in 2010

There are now three hydroelectricity plants larger than 10 GW: the Three Gorges Dam in China, Itaipu Dam across the Brazil/Paraguay border, and Guri Dam in Venezuela.

SOLAR ENERGY

Solar energy, radiant light and heat from the sun, is harnessed using a range of ever-evolving technologies such as solar heating, solar photovoltaic's , solar thermal electricity, solar architecture and artificial photosynthesis.

Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP).

It is a clean , non pollution , ever lasting fuel.

BIO MASS Biomass is biological material derived from living, or recently living organisms. It most

often refers to plants or plant-derived materials which are specifically called lignocelluloses biomass.

As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel. Conversion of biomass to biofuel can be achieved by different methods which are broadly classified into: thermal, chemical, and biochemical methods.

Wood remains the largest biomass energy source today

Biomass can be converted to other usable forms of energy like methane gas or transportation fuels like ethanol and biodiesel for the purpose of energy production.

GEOTHERMAL ENERGY

Geothermal energy is from thermal energy generated and stored in the Earth.

Thermal energy is the energy that determines the temperature of matter. Earth's geothermal energy originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%).

The heat that is used for geothermal energy can be from deep within the Earth, all the way down to Earth’s core – 4,000 miles (6,400 km) down.

INDIA IN FIELD OF RENEWABLE ENERGY RESOURSES

India was the first country in the world to set up a ministry of non-conventional energy resources, in early 1980s

India's cumulative Grid interactive or Grid Tied Renewable Energy Capacity (excluding Large Hydro) has reached 29.9 GW, of which 68.9% comes from wind, while solar PV contributed nearly 4.59% of the Renewable Energy installed capacity in India.
