Total Solar Energy Consumption Globally Our Solar Energy The efficiency of thermonuclear fusion is a major reason the sun has kept radiating heat for so long—the energy released by turning just one kilogram of hydrogen into helium is the same as. The sun burns hydrogen — a lot of it, several hundred million tons per second. but don’t worry; there’s plenty more where that came from; by most estimates, the sun has enough fuel for about.
Ppt Solar And Alternative Energy Powerpoint Presentation Free After about a billion years the sun will become hot enough to boil our oceans. the sun is currently classified as a “main sequence” star. this means that it is in the most stable part of its. The sun produces a large amount of energy by combining very light elements such as hydrogen to heavier elements such as helium and then lithium, oxygen, carbon, right up to iron. they combine because, once you get the nuclei sufficiently close together, there is a very strong attractive force called the nuclear force which holds them together. The core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius. by 30%. The size of the sun is a balance between the outward pressure made by the release of energy from nuclear fusion and the inward pull of gravity. the sun has enough hydrogen fuel to "burn" for a little over 5 billion years but will continue to burn for at least 5 billion more years after that fuel is depleted [source: national geographic].

Photograph. photograph. photograph. article. vocabulary. the sun is the closest star to earth. even at a distance of 150 million kilometers (93 million miles), its gravitational pull holds the planet in orbit. it radiates light and heat, or solar energy, which makes it possible for life to exist on earth. plants need sunlight to grow. In depth. the sun is a 4.5 billion year old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. it’s about 93 million miles (150 million kilometers) from earth and it’s our solar system’s only star. without the sun’s energy, life as we know it could not exist on our home planet.
