7% of global electricity is generated from Solar

Solar energy harnesses the power of the sun to generate electricity, offering a sustainable and almost inexhaustible source of power. This clean energy source is derived from the sun's radiation, which can be converted into electricity or heat. With technological advancements, solar panels have become more efficient in capturing sunlight and converting it into usable energy, making solar an integral part of the global shift toward low-carbon solutions. As the world becomes increasingly aware of the growing need to combat climate change, solar energy stands out as a bright beacon in the array of green energy options.

The process of generating electricity from solar energy primarily involves photovoltaic (PV) systems, which use solar panels made from semiconductor materials, typically silicon. When sunlight strikes these panels, it excites electrons within the semiconductor material, creating an electric current. This direct current (DC) can be converted into alternating current (AC) using inverters, making it compatible with the electricity grid. Utility-scale solar installations and rooftop solar systems alike contribute to this clean energy production, helping to reduce reliance on fossil fuels and lower greenhouse gas emissions.

Solar energy offers significant advantages, particularly in its low carbon intensity, which is approximately 45 gCO2eq/kWh. This is considerably lower than fossil fuels, with coal at 820 and natural gas at 490 gCO2eq/kWh, exemplifying solar's potential to drastically reduce greenhouse gases and mitigate climate change. When compared to other low-carbon energy sources such as wind (11 gCO2eq/kWh) and nuclear (12 gCO2eq/kWh), solar energy is part of a broader suite of clean, sustainable technologies essential for a greener future.

The global contribution of solar energy is noteworthy, with solar generating almost 7% of all electricity consumed worldwide. This reflects a growing adoption and installation of solar infrastructure across various regions, aligned with the urgent push towards low-carbon electricity. In specific areas, solar has become a considerable part of the electricity mix, demonstrating its viability and advantages. In Nevada, for instance, 27% of electricity is from solar, in New Mexico, 11%, in Australia, 18%, in Arizona, 9%, and in Utah, 14%. These figures underscore the potential for even greater expansion of solar infrastructure and its significant role in clean energy generation.

Overall, solar energy, alongside nuclear and wind power, represents a powerful trio of low-carbon electricity sources essential for sustainable development. These technologies significantly contribute to reducing the impact of air pollution and climate change caused by the continued use of fossil fuels. With their lower carbon emissions and ability to generate clean electricity, enhancing the deployment of solar and nuclear energy strategies worldwide could play a pivotal role in achieving a sustainable and bright energy future. Embracing these technologies not only addresses current environmental concerns but also ensures an adequate, secure supply of electricity to meet future demands.
