What is renewable energy? and what are the benifits?

Renewable energy is the energy that can be obtained from natural resources. There are many different types of renewable energy, including wind, solar, geothermal and hydroelectric power. Renewable energy sources can be used to generate electricity or to heat homes and buildings. Solar power is one form of renewable energy that uses photovoltaic (PV) cells to convert sunlight into electricity in bulk quantities. Large solar power plants have enough capacity to supply electricity for small towns or even cities in some cases.

Renewable energy is the energy that can be obtained from natural resources. Some examples of renewable energy sources are:

  • The sun’s rays provide us with renewable energy as they come down to Earth in the form of visible light.
  • Wind is generated by air moving across the surface of our planet and acting upon different objects, such as trees or buildings, which causes them to vibrate at different frequencies depending on how fast the wind blows and what type of object it strikes (e.g., soft versus hard).

Wind, solar, geothermal, hydroelectric and tidal are some examples of renewable energy sources.

  • Renewable energy sources are natural resources that can be replenished.
  • Wind, solar, geothermal, hydroelectric and tidal are examples of renewable energy sources.
  • Renewable energy is a cleaner alternative to fossil fuels like coal or oil because it doesn’t produce climate-changing greenhouse gases when it’s used to generate electricity or heat homes and businesses.

The sun’s rays provide us with renewable energy as they come down to Earth in the form of visible light.

The sun’s rays are photons that provide us with renewable energy as they come down to Earth in the form of visible light. This is just one part of the electromagnetic spectrum, which also includes radio waves, microwaves and x-rays.

The sun is a star–one of billions in our galaxy alone–and its output of energy is constant at about 3.8 x 10^26 watts (38 zeros). In comparison, all other sources of power on Earth add up to less than 1% of this total solar output!

Solar energy can be converted into other forms of energy such as electric power and heat through photovoltaic (PV) cells, which are similar to cells that convert chemical energy into electrical energy in batteries.

Solar energy can be converted into other forms of energy such as electric power and heat through photovoltaic (PV) cells, which are similar to cells that convert chemical energy into electrical energy in batteries. PV cells are made of semiconductor materials that generate an electric current when exposed to light or other electromagnetic radiation.

PV cells have been around since the 1950s and were used on spacecrafts before they became commercially available for use on Earth. Today’s PV technology uses silicon as its main component because it is abundant, easy to work with and inexpensive compared with other materials like cadmium telluride or copper indium gallium selenide (CIGS). The two types of PV technologies include crystalline silicon (c-Si) and thin film technologies such as amorphous silicon (a-Si), cadmium telluride/cadmium sulfide (CdTe/CdS) or copper indium gallium selenide/gallium arsenide phosphide alloy (CuInGaSe2/GaAsP).

A large solar power plant includes panels of PV cells and other equipment needed to convert sunlight into electricity in bulk quantities.

The solar panels are made up of photovoltaic cells, which convert sunlight into electricity in bulk quantities. The electricity is then collected and distributed to the grid for use by other customers.

Some large solar power plants have enough capacity to supply electricity to small towns or even cities.

  • Solar power plants are not designed to supply electricity to individual homes. They are designed to supply electricity to whole towns or cities, although some large solar power plants have enough capacity to supply electricity for small towns or even cities.
  • Large solar power plants can be found in countries such as the United States, China and India.

A wind turbine converts wind power into electrical power by using fans that spin around a coil of wire connected to a generator inside the machine.

A wind turbine converts wind power into electrical power by using fans that spin around a coil of wire connected to a generator inside the machine. Wind turbines are used to generate electricity from the kinetic energy of the wind, which is converted into mechanical energy by a rotor blade mounted on top of a tower (sometimes called an ‘aerial’).

The generator is powered by magnets that cause coils of wire wrapped around it to move up and down as electricity flows through them.

The stator is a coil of wire wrapped around an iron core. The rotor spins around the stator, causing it to move up and down as electricity flows through it. This motion induces a current in the wires of your home’s electrical system that can be used to power lights and appliances (and charge batteries).

As the magnetic field changes direction during this process, it induces a current in another coil of wire attached to an electrical grid system on land or at sea.

As the magnetic field changes direction during this process, it induces a current in another coil of wire attached to an electrical grid system on land or at sea. The coil moves up and down inside a magnet, which generates electricity when it passes through the magnetic field. This electricity then travels along power lines to homes and businesses where we use it for everyday tasks like cooking food or turning on lights.

Conclusion

Renewable energy is a sustainable resource that can be used over and over again. It helps reduce our dependence on fossil fuels and other non-renewable sources of energy such as coal and oil.
