Energy obtained from natural resources that are renewed more quickly than they are used up is referred to as renewable energy. Such sources that are continually replenished include the sun and the wind, for instance. There are several renewable energy sources all around us.On the other hand, non-renewable fossil fuels like coal, oil, and gas require hundreds of millions of years to create. When fossil fuels are used to create energy, they emit dangerous greenhouse gases like carbon dioxide.

More emissions are produced by burning fossil fuels than by producing electricity from renewable sources. The key to solving the climate catastrophe is switching from fossil fuels, which now produce the majority of emissions, to renewable energy.
SOLAR ENERGY:
The most plentiful source of energy is solar energy, which may even be used under overcast conditions. The pace at which the Earth absorbs solar energy is around 10,000 times higher than the rate at which people use energy.
For a wide range of uses, solar systems can provide heat, cooling, natural lighting, power, and fuels. Solar technologies can use photovoltaic panels or solar radiation-concentrating mirrors to turn sunlight into electrical energy.
Although not all nations have the same access to solar energy, direct solar energy may nevertheless make a major contribution to any nation's energy mix. In the past 10 years, the cost of producing solar panels has fallen precipitously, making them not only accessible but frequently the cheapest source of power. Depending on the type of material used in production, solar panels have a lifespan of around 30 years and come in a range of colors.

WIND ENERGY:

By placing massive wind turbines on land, in freshwater, or on the ocean floor, wind energy captures the kinetic energy of flowing air (offshore). Although wind energy has been utilized for thousands of years, onshore and offshore wind energy technology have advanced in recent years to optimize the amount of power generated, using higher turbines and bigger rotor diameters.The world's technical potential for wind energy exceeds that of global electricity production, despite the fact that average wind speeds vary widely by location, and there is sufficient potential in the majority of the world's regions to allow for the deployment of significant amounts of wind energy.Strong winds are present over most of the planet, yet occasionally distant areas are the greatest for producing wind energy. Significant potential exists for offshore wind energy.

GEOTHERMAL ENERGY:

Hydrothermal reservoirs are naturally sufficiently hot and permeable reservoirs, whereas enhanced geothermal systems are naturally sufficiently hot reservoirs that have undergone hydraulic stimulation.Upon reaching the surface, fluids with a range of temperatures can be utilized to produce electricity. Since it has been in use for more than a century, the hydrothermal reservoir power generating technique is well-established and trustworthy.

HYDROPOWER:

The energy of water flowing from higher elevations to lower elevations is captured by hydropower. It can be produced by rivers and reservoirs. Run-of-river hydropower facilities rely on the river's available flow, whereas reservoir hydropower plants use water that has been stored in a reservoir.In addition to supplying electricity, hydropower reservoirs frequently serve as sources of drinking water, irrigation water, flood and drought control, navigation services, and energy.The greatest renewable energy source in the electrical sector at the moment is hydropower. It depends on relatively consistent rainfall patterns, which can be adversely affected by droughts brought on by climate change or by changes to ecosystems that affect rainfall patterns.Hydropower infrastructure also has the potential to negatively affect ecosystems. Because of this, many people believe small-scale hydro is a better

OCEAN ENERGY:

Ocean energy is derived from processes that employ the kinetic and thermal energy of the sea—such as waves or currents—to generate power or heat.Wave and tidal current prototypes are being investigated, however ocean energy systems are still in the early stages of development. Theoretically, ocean energy could easily meet all of the energy needs of people today.
