Discover Renewable Energy
Renewable energy, sometimes known as clean energy, is generated from
naturally replenished sources or processes. Sunlight and wind, for example,
continue to shine and blow despite the fact that their availability is dependent
on time and weather. While harnessing nature's power is typically considered of
as a novel technology, it has long been utilized for heating, transportation,
lighting, and other purposes. Wind has propelled ships across the oceans and
mills that process grain. The sun has supplied warmth throughout the day and
has assisted in the lighting of fires that will linger into the evening.
However, during the last 500 years or more, mankind has increasingly resorted
to dirtier, cheaper energy sources like coal and fracking gas.
Types of Renewable Energy
Biomass Energy: Biomass is a renewable energy source because organic
matter can be renewed in a very short period of time. It's also a pretty
popular one; if you've ever cooked on a charcoal grill or burnt wood in a
fireplace, you've utilized biomass energy. Agricultural crops and waste
products are also examples of Biomass energy. Biomass generated around 5% of
total primary energy usage in the United States in 2020. Biomass energy has a
global installed capacity of 143,370 MW in 2021.
Solar Energy: Solar Energy is the conversion of
solar energy into thermal or electrical energy. Solar energy is the cleanest
and most prolific renewable energy source, and the United States boasts some of
the world's most important solar resources. Solar energy may be harnessed in
three ways: photovoltaics, solar heating and cooling, and concentrating solar
power. Solar energy has been installed in the United States in excess of 121
gigawatts (GW), enough to power 23.3 million households. The solar market in
the United States has risen at an annual pace of 33 percent on average over the
previous decade. In 2021, the global installed capacity of Solar energy is
849,473 MW.
Wind Energy: The kinetic energy generated by wind in
movement is utilized to generate electricity. Wind turbines or wind energy
conversion systems convert this into electrical energy. The blades of a turbine
are initially impacted by the wind, which causes them to revolve and turn the
turbine linked to them. Offshore and onshore wind power are the two forms of
wind power. In 2021, the global installed capacity of wind energy is 824,874
MW.
Hydroelectric Energy:
In the United States, hydropower is the most common renewable energy source for
electricity, however wind energy is likely to overtake it shortly. Hydropower
uses water to generate energy by spinning turbine blades in a generator.
Hydroelectric power has a global installed capacity of 1.23 million MW in 2021.
Geothermal Energy: Geothermal energy is heat obtained from
the earth's subsurface. The geothermal energy is carried to the Earth's surface
via water and/or steam. Geothermal energy can be utilized for heating and
cooling or for generating clean power, depending on its features. For power,
however, high or medium temperature resources are required, which are typically
found near tectonically active areas. In 2021, geothermal energy has a global
installed capacity of 15,644 MW.
Ocean Energy: Ocean energy is an
unlimited, renewable source of energy. Ocean energy systems generate
electricity by harnessing the strength of tides and waves, as well as changes
in water temperature and salinity. Tide Stream, Wave Energy, OTEC & SWAC,
and Tidal Range are the main kinds of ocean energy. Ocean energy has a global
installed capacity of 524 MW in 2021.
Significance
of Renewable Energy
When carbon dioxide emissions are reduced to zero, the global
temperature will stabilize. This entails attaining net zero carbon dioxide
emissions globally in the early 2050s for 1.5°C (2.7°F) and the early 2070s for
2°C (3.6°F). Keeping global warming below 2°C (3.6°F) still necessitates a peak
in global greenhouse gas emissions by 2025 at the latest, and a quarter
reduction by 2030. Renewable energy is frequently at the top of any list of
adjustments the world can make to mitigate the worst consequences of increasing
temperatures in any conversation about climate change. This is due to the fact
that renewable energy sources like sun and wind do not create carbon dioxide or
other greenhouse gases, which contribute to global warming.
