What is renewable energy?

Renewable energy is energy derived from natural sources that are replenished
at a higher rate than they are consumed. for example Sunlight and wind, are
such sources that are constantly being replenished
SOLAR ENERGY

Solar energy is any type of energy generated by the sun. Solar
energy is created by nuclear fusion that takes place in the sun.
Fusion occurs when protons of hydrogen atoms collide in the
sun's core and fuse to create a helium atom.

Energy direct from the sun is also known as solar energy.

The sun’s rays shine on a large array of solar cells also known as
solar panels, The solar cells absorb the energy of the rays, and
electricity is produces
Advantages of Solar Energy
•
Solar energy is a renewable energy source and reduces carbon emissions. ...
•
​Solar energy can reduce your home's electricity bill. ...
•
Solar power can get you money back through Solar Renewable Energy Credits
(SRECs) ...
•
Homes with solar panels installed may improve home value.
Disadvantages of solar energy
: Needs a lot of space.
: High initial cost.
: Less solar energy in winter.
: Dc equipment is expensive.
WIND ENERGY
Wind power or wind energy describes the process by which
the wind is used to generate mechanical power or electricity.
Wind turbines convert the kinetic energy in the wind into
mechanical power.
Wind is renewable and does not contribute to global
Warming. It is unreliable because the speed of the wind
Can vary and on calm days no power is produced The

ADVANTAGES OF WIND ENERGY
: Wind power creates good-paying jobs.
: Wind power is a domestic resource.
: Wind power is a clean and renewable energy source.
: Wind power benefits local communities.
: Wind power is cost-effective.
: Wind turbines work in different settings.
DISADVANTAGES OF WIND ENERGY
•Wind power must compete with other low-cost energy sources. ...
•Ideal wind sites are often in remote locations. ...
•Turbines produce noise and alter visual aesthetics. ...
•Wind plants can impact local wildlife.
WAVE POWER
Wave energy (or wave power) is the transport and
capture of energy by ocean surface waves. The
energy captured is then used for all different kinds of
useful work, including electricity generation, water
desalination, and pumping of water.
Wave power is renewable and does not contribute to
global warming.
Most of the energy of winds is transferred to the sea
as waves are formed by friction between wind and
water.
ADVANTAGES OF WAVE POWER
•
Renewable. The best thing about wave energy is that it will never run out.
•
Environment Friendly.
•
Abundant and Widely Available.
•
Variety of Ways To Harness.
•
Easily Predictable.
•
No Damage to Land.
DISADVANTAGES
•
Suitable for Certain Locations.
•
Effect on Marine Ecosystem.
•
Weak Performance in Rough Weather.
•
Noise and Visual Pollution.
•
High Cost.
