Your Questions About Sustainable Energy Systems
William asks…
How do places with wind and solar energy sustain their power?
Some places rely on solar and wind energy right? To power their homes and such. How do they use energy in the night or when there is no wind? Do they have something that stores the energy like a big battery or something?
I have to “make” a green city and it will use renewable energy source including solar and wind energy. How would I make the wind and solar energy sustainable and not have shortages of power?
admin answers:
Small places, like a remote house or an island, might have batteries. A large place, like a city, would be connected to a “Grid”, or electrical energy transmission system. If the wind stopped blowing, deep in the night, they would pull energy off the grid, from a nuclear plant, or coal-burning generation station, or hydroelectric project many miles away. A town on an island might have a large diesel generator.
Robert asks…
What are the opportunities in bio energy systems in developing countries?
I want to know about what is a bio energy system, bio energy resources available in tropical developing countries and how those resources are used for producing energy. Please describe impacts of usage of such energy related to fields of economics, social, environment and sustainable use also.

Borneo has wiped huge rain forest to plant palm plants for palm biodiesel. The net effect is that the CO2 released from slash and burn will never be taken back into the biosphere, so its a net CO2 increase.
