7% of global electricity is generated from Solar

Solar energy is a form of power derived from the sun's radiation. It is a sustainable and abundant resource that can be harnessed to produce electricity, heat water, and power machines. Unlike fossil fuels such as coal and oil, solar energy is virtually inexhaustible, and its use does not emit harmful pollutants into the atmosphere. With technological advancements in solar photovoltaic (PV) cells and solar thermal systems, capturing and converting solar power into usable energy has become increasingly efficient and economically viable. This form of clean energy plays a crucial role in global efforts to transition towards more sustainable energy production and combat climate change.

Electricity generation from solar energy is primarily achieved through photovoltaic (PV) cells, which convert sunlight directly into electricity. These cells are made from semiconductor materials, such as silicon, that absorb photons from sunlight and release electrons, thus generating an electric current. Solar power can also be harnessed through concentrated solar power (CSP) systems, which use mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small area. The concentrated energy is used to produce steam that drives a turbine connected to an electrical generator. Both methods are integral to a diverse and sustainable power grid that prioritizes low-carbon energy sources.

One of the most significant advantages of solar energy is its notably low carbon intensity. With an average carbon intensity of 45 gCO2eq/kWh, solar energy is a low-carbon power source that considerably reduces greenhouse gas emissions compared to fossil fuels. For context, coal has a carbon intensity of 820 gCO2eq/kWh, and gas has 490 gCO2eq/kWh, both of which contribute substantially to climate change and air pollution. In comparison, solar energy, along with other clean sources like wind (11 gCO2eq/kWh) and nuclear (12 gCO2eq/kWh), showcases the potential for a cleaner, healthier environment.

The adoption of solar energy is growing globally with notable examples. Solar energy contributes to 6.91% of all the electricity consumed worldwide, a number that continues to grow. Certain regions have made significant strides, such as Nevada, where solar accounts for 29% of electricity generation, and Australia, with 21% of its electricity derived from solar power. This trend is mirrored in several other areas, including New Mexico (13%), Arizona (11%), and the Netherlands (21%), all of which illustrate a promising shift toward clean electricity.

As we celebrate the expansion of solar energy, it is important to mention other pivotal low-carbon energy sources like wind and nuclear. These clean technologies also provide highly efficient and sustainable energy solutions. Together, wind, nuclear, and solar represent the vanguard of the low-carbon energy transition. Building and expanding infrastructure for these energy sources is essential to addressing burgeoning electricity demands and striving for a sustainable future. With concerted efforts to expand solar and nuclear energy, we can move closer to achieving a global energy system that prioritizes environmental health and leads to substantial reductions in carbon emissions.
