This video explained well about solar panels, history of solar power and efficiency of solar power.

CAN SOLAR SAVE US? - PROBABLY, EVENTUALLY, WITH LOTS OF GOVERNMENT HELP.

Nowadays, there are many efforts to find efficient ways to save the environment. Since humans have used some parts of science worngly, they think it's time to cure the Earth. AFter scientists researched many studies, alternative energies were found and used society.

One of the most efficient and good alternative energies is uing the sunlight which is called 'Solar Energy'. Since people have used fossil-fuels too much, the environment became worse. Using fossil-fuels such as coal or oil emits lot of carbon dioxide (CO2) which results in golbal warming. So, peopl are studying more about Solar Energy which is renewable and can be used a s an alternative.

Another benefit of solar energy is that there is no limitation. Since the Sun will always shine on the Earth, solar energy is free and there is no limitation to using it. So, excluding the worst hypothesis-if the SUn stops shining on the Earth foreever, this is a very good solution to global warming. Solar Energy is also Independent and it doesn't require much work from jumans since the Sun shines by itself. Of course, this energy is not as harmful as using fossil-fuels.

However, there are also side effects from this source of energy. Solar Powered equipment is the most expensive to build from all alternative energies. Humans also have to consider the area which they might install solar powered machines in and think about the fact that a tnight, there is no production of sunlight.

We don't know how much help that Solar Power Energy can help us instead of using fossil-fuels yet, but I'm sure that the environment won't worry anymore since there is much effort by humans for it.
