Hey friend,
☆☆☆THE SOLAR POWER: ULITMATE ENERGY SOLUTION☆☆☆
Every day we are able to see sun rises in the morning and sets in the evening. In this day time, the sun gives use heat energy. It gives temperature to the earth. It is sometimes increased sometimes decreases. But still, We won't be able to survive without sun light. Yeah! it is an essential source for existing life.
We are aware of the sun. We had studied from our lower classes. We know sun is a ball of fire. But some may not know how is this sun burns like a fire and gives sunlight radiations. We maynot know about a process which sun undergoes. Ok now let's see it. Deep in the core of sun, hydrogen atoms react by nuclear fusion, producing a massive amount of energy that streams in all directions at the speed of light. In fraction of minutes, That means in eight minutes that energy travels 93 million miles to earth.

SOLAR ENERGY: THE ULTIMATE POWER SOURCE

Every morning the sun rises, bringing light and heat to the earth, and every evening it sets. It seems so commonplace that we rarely spare a thought for that bright object in the sky. Yet without it, we wouldn’t exist!
Deep in the core of our local star, hydrogen atoms react by nuclear fusion, producing a massive amount of energy that streams in all directions at the speed of light (that’s the mind-boggling speed of more than 186,000 miles per second). In just eight minutes, that energy travels 93 million miles to earth.
We use different forms of energy, but almost all of the energy emerges with the sun, not just light and heat energy. The law of conservation of energy says that "Energy can’t be created or destroyed, but can change its form". And that only happens with energy from the sun—it changes into lots of different forms like,
* Plants convert light energy from the sun into chemical energy by the process of photosynthesis. Animals eat plants and use that same chemical energy.
* Hydroelectricity is electrical energy produced from moving water, and water flows because heat energy from the sun causes evaporation that keeps water moving through the water cycle.
* Human activity uses energy from fossil fuels such as coal, oil, and natural gas. These energy sources are created over very long periods of time and fossilized the living matter and the energy in that living matter actually came from the sun through photosynthesis.
* Heat energy from the sun causes changing weather patterns. Wind turbines then convert wind power into electrical energy.
From this we can say solar power is an ultimate energy solution. Infact in additional solar panels are used to power many things like emergency signs, school crossing lights, etc. Many people are also able to power their homes by mounting solar panels on the roof, and this will only get easier as the technology continues to advance.
Hope my answer helps you :)
