Energy sources is divided into 2 viz renewable (such as solar, wind, hydrothermal energy) and non renewable resources (like fossil fuels). We should try to more use renewable energy resources which not only saves non renewable energy but also helps in reducing polution in our environment.

With thanks

We have to perform elaborate research on SUN and WATER (Hydrogen gas) to get energy in future days.

Good responses @all

Hello,

I personally think that the level of energy consumption can be wisely determined based on several factors. Firstly, the consideration of future generations and their accessibility to such energies. Second, the extent to which energy consumption contaminates the ecological system. The last but not least, the trade off between cost and efficiency.

Best regards

Dear All,

The most important thing is to be grown up and to be educated as not to waste energy and material, and to economize the most strictly with energy. Our tragedy is, that billions of people waste energy for their pleasure and hobby practically almost for nothing.

I appreciate my colleagues answers.
