"How do we use the sun as a source of energy?"
The sun gives off a power called "Nuclear Fusion". It is the hearty of the sun's power. Nearly everything on earth is indirectly powered by this power reaction.
The sun raidiate light, heat or solar energy, which makes it possible for life to exist on earth. Plants need sunlight to grow. Animals, including humans need plants for food and oxygen they produce. Without heat from the sun, the earth will freeze.
We use a lot of the sun's energy for cultivating land, producing crops, and raising livestock. The sun is also used for solar architecture which stores heat. Buildings have windows and skylights for air circulation. Other aspects include using selective shading and choosing building materials with thermal mass. And example is a greenhouse. Greenhouses create a environment for growing that otherwise isn't available in that location. You can also use solar energy to cook, and heat water in solar cookers. Solar cells can also convert sunlight directly into electricity. They don't produce much so they have to be grouped together in large numbers. Solar cells are used for everything from calculators and watches to homes, commercial buildings, and even stadiums. The sun offers clean, free energy in abundance. It gives us more energy than we could ever need. Time to use it.
