renewable sources
TRANSCRIPT
Energy is the power to do works and drive machine. Energy cannot be made or destroyed , regarding motion,
there are kinetic and potential energy Regarding power there are two kinds of energy
1.Renewable energy
2.Non-renewable energy
INTRODUCTION
Most renewable energy comes either by directly or indirectly from the sun.
Sunlight or solar energy , can be directly for heating and lighting homes and other buildings , for generating electricity.
Solar radiation is radiant energy emitted by the sun , particularly electromagnetic energy. About half of the energy is in the visible.
Solar technologies are generally classified as active and passive solar energy.
Solar Energy
When sunlight is absorbed by the materials , the solar energy knocks electron loose from their atoms , allowing the electrons to flow through the material to produce electricity.
Several connected PV arrays can provide enough power for a household ; for large electric utility or industrial applications , hundreds of arrays can be interconnected to form a single , large PV systems.
Photovoltaic (PV) Effect
Solar balloons has been made for consuming energy. 500 watt to 1 kilowatt energy from single balloon. This technology is named as concentrated photo voltaic
(CPV) technology.
Solar Balloons
It converting wind energy into electricity by using wind turbines.
Wind comes from atmospheric changes; changes in temperature and pressure makes the air move around the surface of the earth.
A wind turbine captures the wind to produce energy. It create power without using fossil fuels without producing
green house gases or radioactive toxic waste. Wind power is one of the best way to combat global warming.
Wind power
Synthetic solar cells created on tobacco plants. Electricity from bacteria and grass clippings. Virus battery. Energy from cactus. Living batteries. Harvesting energy from spinach. Energy to run LEDs harvested from trees. Generating energy from trees to power sensors.

Applications of renewable sources
Renewable energy technologies can help to contribute to a clean and secure energy for our nation and the world.
Our earth.
We have to make a balance between energy consumptions and environment protection.
We have to make more efforts to ensure that the world’s resources are to be used in a sustainable energy.
