Renewable sources

Renewable energy sources are a source of energy that is environmentally friendly. Energy can be recovered and does not leave behind dirt, exhaust gases or toxic waste. So they are more secure techniques that have a better impact on the environment in which we live.

They are renewable, meaning that their use is unlimited, because in nature they are constantly replaced, so they can be used again and again without losing their value. We can convert renewable sources to form of energy that we use every day .

We can make renewable energy from renewable sources. It is made from natural resources such as sunlight, wind, rain, tides, waves and geothermal heat. About 16% of global final energy consumption comes from renewables, with 10% coming from traditional biomass, which is mainly used for heating, and 3,4% from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) account for another 3% and are growing very rapidly.

  

TIPES OF RENEWABLE ENERGY

·Solar energy

We can use solar cells to exploit the sunlight. It's an inexhaustible source or renewable energy that provides an important part of the energy that we need.

·Hydro energy

It is a renewable source of energy, which is durable, natural and constantly replaced. It is clean energy, because the operation of hydroelectric power plants will not produce CO2 emission or pollution.

·Wind energy

Electrical energy can be derived from wind power. Wind energy is a collective term for the processes of energy collected from the movement of air masses. The most common example is a windmill system that converts wind energy into mechanical or electrical energy.

·Biomass

Biomass is biological material from living, or recently living organisms, mostly from plants  or plant-derived materials. As a renewable energy sourc, biomass can be used directly, or indirectly or converted into another type of energy product such as biofuel. Biomass can be converted to energy in three ways: thermal conversion, chemical conversion, and biochemical conversion. It can be grinded in to chips, or squeezed into pellets.

·Geothermal energy

Thermo energy is energy from the earth. It is mostly used for heating houses. You can also use it for taking a shower, but then the temperature of the water must be higher. In that situation you will need other energy to heat the water more, to avoid the development of health-threatening.
