Energy is generated in the interior of the Sun through sequences of nuclear reactions in which four protons fuse together to form a helium-4 nucleus. These sequences are accompanied by the release of two particles known as electron neutrinos. Models suggest that 99% of the nuclear energy ...
But Greece is fighting back – pushing for a transition to clean energy and carbon neutrality by producing renewables at record levels. "September 6 was a day of records for the Greek renewable sector: 81 percent of the total clean energy in the country was provided by wi...
Stories Energy explained How does solar power work? Solar power works by converting energy from the sun into power. There are two forms of energy generated from the sun for our use – electricity and heat. Both are generated through the use of solar panels, which range in size from reside...
Using a solar cooker, we can do the same things, but by using sunlight instead of gas or electricity. Sunlight isn't hot in and of itself. It's just radiation, or light waves -- basically energy generated by fluctuating electric and magnetic fields. It feels warm on your skin, but ...
The European nation’s energy revolution has made it a leader in replacing nukes and fossil fuels with wind and solar technology.
A solar inverter is essential to any solar system. Because the electricity generated by solar panels is direct current (DC), you need to convert the electricity to alternating current (AC) to use it in your home. There are different types of inverters for solar use (string, central, micro...
In South Africa, solar power has seen rapid growth. With an abundance of sunshine, solar energy offers a sustainable and practical solution for both homes and businesses. However, one of the challenges is that solar power canonly be generated during the day, and efficiency can vary depending ...
Energy storage systems enable cost savings and efficient use of renewable power, even after it’s been generated.
But how does the efficiency of thin-film solar cells compare to traditional cells? The theoretical maximum for silicon-wafer cells is about 50 percent efficiency, meaning that half of the energy striking the cell gets converted into electricity. In reality, silicon-wafer cells achieve, on average...
Energy cannot be lost or created, so what happens to human life after death?The light from the Sun is essential for all life on Earth. For a long time, we did not understand where all of this energy is coming from and how the sunlig...
