6% of global electricity is generated from Solar

Solar energy is harnessed by capturing sunlight and converting it into electrical power. This form of energy relies on solar panels, which are comprised of photovoltaic cells that directly convert sunlight into electricity. Unlike traditional fossil fuels, solar energy utilizes an abundant and renewable natural resource—the sun—making it a cornerstone of sustainable energy solutions.

The process of generating electricity from solar energy begins with photovoltaic cells in the solar panels. When sunlight hits these cells, it excites electrons and generates an electric current through the photovoltaic effect. This direct current (DC) electricity is then converted into alternating current (AC) through an inverter, making it compatible with the electrical grids and household appliances. This method is clean and efficient, with minimal environmental impact.

One of the largest advantages of solar energy is its low carbon intensity. Solar energy has an average carbon intensity of just 45 g CO2eq/kWh, far better than fossil fuels like coal (820 g CO2eq/kWh) and gas (490 g CO2eq/kWh). Other low-carbon energy sources, such as wind (11 g CO2eq/kWh) and nuclear (12 g CO2eq/kWh), also share similarly low carbon footprints. Together, these clean technologies can significantly reduce greenhouse gas emissions and combat climate change.

Globally, solar energy plays a substantial role in electricity generation, contributing 6.27% of all electricity consumed. Certain countries have made remarkable progress with solar energy integration. For instance, in Australia, solar energy accounts for 19% of the electricity, while in the United Arab Emirates, it makes up 8%. European nations also show promising solar adoption, with the Netherlands and Spain generating 19% and 18% of their electricity from solar, respectively. In Greece, solar energy contributes an impressive 22% to the national electricity mix.

The increasing adoption of solar energy—a significant source of clean energy—adds another layer of urgency in moving away from fossil fuels, which are major contributors to climate change and air pollution. Alongside solar, wind and nuclear energy provide complementary solutions to achieve a sustainable and green energy future. Together, these low-carbon technologies can form the backbone of a resilient and eco-friendly electricity grid on a global scale.
