sources of energy

Solar Energy is cleanest and one of the cleanest sources of energy.

Solar Power depends on sunlight,so in cloudy weather and at night. No power is generated.

Wind energy is non-polluting but is only useful in places where there is a lot of wind.

Wind turbines convert the kinetic energy of the wind into mechanical power.

Nuclear energy is efficient and doesn't produce carbon gases as a waste product.

The danger of nuclear power include deadly radioactive waste product.

A major source of energy comes from the burning of fossil fuel such as coal and oil.

When we burn fossil fuels waste gases such as co2 are produce.

Fossil fuel remain the largest source of energy of most country.

Hydro power  comes from the kinetic energy of falling water.

Output is reliable and can be regulated to meet the demand expect during the period of drought.
