the sun
The sun is our principal source of energy. Solar radiation provides light and heat energy that powers various natural processes on Earth, such as photosynthesis in plants and the water cycle. This energy is harnessed through solar panels to generate electricity and other forms of renewable energy.
For electricity it is still coal, at about 50 percent. For transport it is oil.
The principal fuel source for living animals is glucose, which is derived from the breakdown of carbohydrates in the diet. Glucose is a primary source of energy for cellular processes and is used by the body to produce ATP, the molecule that powers most biological reactions.
The principal source of stellar energy is nuclear fusion, where hydrogen atoms combine to form helium in the core of a star. This process releases immense amounts of energy in the form of light and heat.
Since the sunis the principal energy source for atmospheric processes, it is critically important. Without the sun, not only would those processes not exist, but the atmosphere would condense and freeze and the planet would be uninhabitable by the forms of life that now exist on it.

The principal end product of photosynthesis is glucose, a simple sugar molecule that serves as the main energy source for plants.
Nuclear energy is used as a source of heat. The heat from the reactor is used to heat up water and the steam moves a turbine that generates electricity. It's the same principal with a coal power plant, only the source of heat is different.
"I refuse to lie as a matter of principle." This word is often confused with, "principal," which means "main" or the head of something, like a school. For that you could say: * The principal called me to detention * Oil is the principal source of energy in the world today
Principal energy levels are an atom's major energy levels, ranging in value from 1 to 7. Energy sublevels are contained within principal energy levels, and their number increases as the value of the principal energy level increases.
A principal source of carbohydrates is plant-based foods, particularly grains, fruits, vegetables, and legumes. Common examples include rice, bread, pasta, potatoes, and fruits like bananas and apples. These foods provide energy and are often rich in fiber, vitamins, and minerals. Carbohydrates are essential for the body's energy needs and play a crucial role in overall health.
The principal source of heat to the Earth's atmosphere is the Sun. Solar radiation heats the Earth's surface, which in turn warms the air above it, creating temperature variations that drive atmospheric circulation. Without the Sun's energy, Earth's atmosphere would be much cooler.
