Renewable Source Of Energy

RENEWABLE

ENERGY

RENEWABLE ENERGY Renewable energy is energy generated from natural resources. Such as. Ø Sunlight Ø Wind Ø Rain Ø Geothermal heat Which are renewable.

About 18% of global final energy consumption came from renewables, Ø13% coming from traditional biomass, such as wood-burning. ØHydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation),followed by solar hot water/heating, which contributed 1.3%. ØModern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some ,0.8% of final energy consumption.

RENEWABLE ENERGY TECHNOLOGIES: 1. WIND POWER 2. WATER POWER 3. SOLAR ENERGY 4. BIOFUEL 5. WAVE POWER 6. HYDRO POWER

SOME FACTS: Wind power is growing at 30% annually with

capacity of 100gw. The majority of renewable energy technologies are powered by the sun. The world's largest geothermal power installation is The Geysers in California, with a rated capacity of 750 MW. Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugar cane, ethanol provides 18 percent of the country's automotive fuel.

Kenya has the world's highest household solar

ownership rate with roughly 30,000 small (20– 100 watt) solar power systems sold per year.

SOLAR ENERGY

Ways to Convert Solar Energy into Electricity… Photovoltaic system. Solar-Thermal Technologies.

Photovoltaic system..

Advantages of Photovoltaic systems…  PV arrays can  be installed quickly

and in any size required or allowed.  The environmental impact is minimal, requiring no water for system cooling and generating no by-products.

WIND POWER What is it?

WIND POWER - What is it?  All renewable energy (except tidal and

geothermal power), ultimately comes from the sun Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines

 About one or 2 percent of this energy is

converted to wind energy (which is about 50100 times more than the energy converted to biomass by all plants on earth

•A wind turbine obtains its power input by converting the force of the wind into a torque (turning force) acting on the rotor blades. •The amount of energy which the wind transfers to the rotor depends on the density of the air, the rotor area, and the wind speed.

How it is Generated Wind power is generarated by using wind mill. A Windmill captures wind energy and then uses a generator to convert it to electrical energy

Advantages of Wind Power •The wind blows day and night, which allows windmills to produce electricity throughout the day. (Faster during the day) •Energy output from a wind turbine will vary as the wind varies, although the most rapid variations will to some extent be compensated for by the inertia of the wind turbine rotor.

GEOTHERMAL ENERGY

GEOTHERMAL = GEO + GEO - EARTH

IT IS A

RENEWABLE ENERGY SOURCE. WATER -RAINFALL HEAT-CONTINUOUSLY PRODUSE INSIDE THE EARTH

THERME - HEAT

DIFFERENT GEOTHERMAL ENERGY SOURCES  HOT WATER RESERVOIRS  NATURAL STEAM RESERVOIRS  GEO PRESSURED RESERVOIRS  NORMAL GEOTHERMAL GRADIENT  HOT DRY ROCK  MOLTEN MAGMA

PLANT

 DRY

SYSTEM TO PRODUCE GEOTHEMAL ENERGY STEAM PLANTS  FLASH STEAM PLANTS  HOT DRY ROCKS  BINARY CYCLE PLANTS

GEOTHERMAL POSITIVE ATTRIBUTES  GEOTHERMAL ENERGY

USE BY 58 COUNTRIES .  IT IS NUMBER THREE OF THE RENEWABLE ENERGY.  83.3 MILLION BARRELS FUEL SAVE EACH YEAR.  IT PREVENTS 40.2 MILLION TONS CO2 EACH YEAR.  IT IS CHEAP IN COMPESSION OF CRUDE ENERGY.

BIO FUEL

BIOFUEL Biofuel is usually either a Bioalcohol ,ethanol

fuel biodiesel or vegetable oil, Biogas and Biomass Biofuel lead to relatively low CO2 omission than

fossil fuels.

BIODIESEL Biodiesel is made by chemically-reacting lipids,

typically vegetable oil or animal and alcohol. Biodiesel can be used in modern diesel vehicles

with little or no modification to the engine.

ETHANOL FUEL

Ethanol are

produced from corn, cornstalks, sugarbeets, sugar cane, and switchgrasses to produce ethanol.

BIOGAS Biogas can easily be produced from current

waste streams, such as paper production, sugar production, sewage, animal waste. Biogas can be utilized for electricity production.

SOLID BIOMASS  Solid biomass is

mostly commonly usually used directly as a combustible fuel.

 Sources include wood

fuel, the biogenic portion of municipal solid waste, or the unused portion of field crops.
