2. RENEWABLE ENERGY:-
• Energy from a source that is not
depleted when used, such as wind or solar
power.
• Types of Renewable Energy
Sources:-
 Biomass Energy
 Wave Energy
 Solar Energy
 Water Energy
 Geothermal Energy
 Wind Energy

3. Solar Energy
Solar energy is radiant light and
heat from the sun that is harnessed
using a range of ever-evolving
technologies such as solar
heating, photovoltaics, solar
thermal energy, solar architecture,
molten salt power plants
and artificial photosynthesis.

4. • As heat for making hot water,
heating buildings, and cooking.
• To generate electricity with
solar cells or heat engines
• To take the salt away from
sea water.
• To use sun rays for drying
clothes and towels.
• It is used by plants for the
process of photosynthesis.

6. Wind energy is a form
of solar energy. Wind
energy(or wind power)
describes the process
by which wind is used
to generate
electricity. Wind turbin
es convert the
kinetic energy in
the wind into
mechanical power. A
generator can convert
mechanical power into
electricity.

7. History Of Wind Energy:-
Wind power has been used as long as
humans have put sails into the wind.
For more than two millennia wind-
powered machines have ground grain
and pumped water. Wind power was
widely available and not confined to
the banks of fast-flowing streams, or
later, requiring sources of fuel. Wind-
powered pumps drained the polders of
the Netherlands, and in arid regions
such as the American mid-west or
the Australian outback, wind
pumps provided water for livestock
and steam engines.

8. In 2018, global wind power capacity grew 9.6% to 591 GW. In 2017, yearly wind energy
production grew 17%, reaching 4.4% of worldwide electric power usage, and providing 11.6% of
the electricity in the European Union. Denmark is the country with the highest penetration of
wind power, with 43.4% of its consumed electricity from wind in 2017. At least 83 other
countries are using wind power to supply their electric power grids.
