Looking at the present situation of earth, the bad state that we have made of it. The extent of pollution that has killed the ecosystem of the earth. Made it devoid of trees, vegetation. Now it’s time to go for alternatives to the present sources. Towards finding and applying renewable sources of energy. There was active participation from companies like Google, Amazon, and AT&T.

The organizers of this protest are suspected to be people of Fridays for the future campaign by CBS News. People of Fridays for the future campaign are those students who walk out of school on Fridays asking their political leaders to take urgent action on climate change.

This campaign can prove historic as people from 150 countries are stepping out of the home to help these young students. The common demand of all people is to stop the use of fossil fuels.

The way it is devastating our earth is terrific. There needs to be a great change taking place which can stop or minimize the use of non-renewable energy. Climate change will go on and on and its stop will never come so the protestors cannot stop.…

Researches are going on to reduce the cost of making solar cells. It is very difficult to decrease down the manufacturing costs. The only thing which can be done in enhancing the efficiency of energy conversion. The present efficiency of energy conversion of Silicon-based photovoltaic panels is 15 to 18%. Scientists have a big ray of hope for the new material Perovskite which is cheap and economic. 

It absorbs moisture or water, in that time they deteriorate, become unstable and decrease the life span of solar panels. Perovskite was made to stick to the material used. The most used material for manufacturing solar panels approximately 92% used is Crystalline Silicon.

The Perovskite is something new and different from the conventionally used semiconductors for solar cells. Some of the great advantages of Perovskite are that they are thin-film technology, which can be easily printed on plastic and flexible substrates. Also, they can be made from the solution. Silicon requires a long process of refinement in the industry then we get the pure silicon.…

Nature has given us an abundance of sources to help us satisfy our demands. There are energy sources available in all kinds of phases. There is the fresh wind, rapidly flowing which can be used to drive windmills. There is the water at high pressure in dams or waterfall, the potential energy stored in it can produce hydel power.

The sun, the ultimate source of energy gives us sunlight that can be stored. These are those things that are already being worked upon and they are in practice, they are already applied. Here we will see how engineers can use their imagination, creativity, technical minds to make much more from the nature around us.

The imitation of nature in every technique or any machine is not a new thing. It started very long back, Ornithopter designed by Leonardo da Vinci was the application of flapping wings of a bird. Renewable energy is finding applications in many parts of our lives.

Engineers and researchers are continuously finding ways to study nature in the respect of wind, sea and solar so that we can make efficient devices. Those which don’t harm the environment.…
