I think such research is desperately needed in order to avert climate disaster.

I think such research is desperately needed in order to avert climate disaster.

The positive side of this research is that it is less harmful for researcher's health.

Those researches are key to our life sustainance. I am into this course of research and I love to protect nature!

Hi,

Solar: This is perhaps the most recognized renewable energy source. Energy from the sun is captured using cells made from special materials (silicon is quite popular right now) and then converted into electricity. The biggest factor in solar cell production is cost. However, with technological advancements solar is becoming more cost efficient, and high efficiency solar cells are being developed.

Wind: Wind power is growing rapidly, and is becoming a well-recognized renewable energy resource. Using wind power to turn turbines that generate electricity can provide a cheap source of energy. Building and maintaining equipment could provide thousands of jobs and cost-efficient and clean electricity. Wind farms, however, are not particularly popular. They can impact local environment and wildlife, and even provide noise pollution. Additionally, many people feel that the equipment used obstructs scenic views.

Geothermal: Geothermal energy is extracted from the natural processes of the earth. A great deal of heat is created below Earth's surface, and efforts are being made to extract and use this power. While the ancient Romans knew about and used geothermal heating, now Earth's processes are being used to generate electricity -- going beyond space heating. Geothermal power does not put off greenhouse gases (although some harmful gases from deep in the earth would be released -- and need to be contained), and it is reliable. However, it can only be used in areas where there is tectonic activity.

Water: We have been studying water-based renewable energy for quite some time. Hydroelectricity has been a source of energy for years. However, even though the energy production process does not put off pollution, there are other environmental concerns associated with the damming of rivers and ecological impacts stemming from this practice. But hydroelectric power remains one of the more cost-efficient means of generating renewable energy.

Nuclear: Perhaps the most controversial form of renewable energy is nuclear energy. Electricity is produced from the energy released by nuclear reactions. While fission (splitting) is the main source used today, interest continues in developing cold fusion. Currently, though, power plants generating power using nuclear fission are among the safest plants. They also generate power without emitting pollution. In Europe, France benefits greatly as its nuclear energy produces the cheapest electricity (according to 60 Minutes).

We should focus research to identify different use (not only charging of cells) of energy of the SUN and on getting Hydrogen from water to use it as fuel.

Environmentally friendly materials and using clean and 

renewable energies can help to create a healthier outdoor and indoor environment.

Thanks for all I think that such research has become very necessary to protect the environment we live in best wishes

Really its much important field of researches and all our colleagues whom have specialist in this field are invited to do their high efforts to save our future generations from the environmental risks that attack us here and there ,, Best regards ,, Jawad Ali

As i think, the researches in this way so important to correct changes in climate and reduce global warming. Regards.

yes ,we efforts must be intensified to this process ...regards

thanks for all

best regards

so thanks dear Paul Olusegun Bankole

best wishes

Excellent question waiting for answer

dear sir Ahmed Ammar

so thanks
