This document discusses various renewable energy sources including sunlight, wind, rain, geothermal heat, biomass, and hydropower. It notes that about 18% of global energy comes from renewables. Modern renewable technologies like wind power, solar power, geothermal energy, and ocean energy provided around 0.8% of final energy consumption globally. The document outlines different renewable energy technologies and provides facts about topics like wind power capacity, Brazil's renewable energy program, and Kenya's solar panel adoption rate. It also discusses various solar energy applications and conversion methods, as well as specific renewable sources like geothermal, biofuel, and biomass energy.

1. RENEWABLE ENERGY

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

3. 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.

6. 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.

7. Kenya has the world's highest household solar
ownership rate with roughly 30,000 small (20–
100 watt) solar power systems sold per year.

14. WIND POWER
What is it?

15. 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 50-
100 times more than the energy converted to
biomass by all plants on earth

16. •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.

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

18. 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.

24. BIO FUEL

25. 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.
BIOFUELBIOFUEL

26. BIODIESELBIODIESEL
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.

27. Ethanol are
produced from
corn, cornstalks,
sugarbeets, sugar
cane, and
switchgrasses to
produce ethanol.
ETHANOLETHANOL
FUELFUEL

28. 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.
BIOGASBIOGAS

29. 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.
