Solar photovoltaic energy has become the cheapest source in the world and is growing at a rapid pace, displacing coal, gas, and nuclear energy.
The price drop has been decisive:
In comparison:
The Sun irradiates more energy in one hour than humanity consumes in a year. With solar panels on less than 1% of the Earth’s surface, the entire world’s energy demand could be covered.
One of the major challenges of solar energy is its intermittency: it only produces electricity when there is sunlight. However, advances in lithium batteries, thermal storage, and hybrid systems are allowing solar energy to become a reliable and continuous source. Storage adds between 2 and 3 cents per kWh but ensures stable supply even during nighttime or cloudy days.
Additionally, integration with smart grids and the development of bifacial panels (which capture energy on both sides) increase efficiency and reduce costs.
Solar energy is emerging as the main global energy source. Researchers from the Lappeenranta University of Technology estimate it could cover up to 76% of global electricity in the future. Its exponential growth, reduced costs, and ability to displace polluting sources make it the cornerstone of the energy transition towards a sustainable model.
