Linda asks…
What are the three counties that use the most energy in the world?
and what are the two that use the least amount of energy? do they use mostly renewable or non-renewable energy? And do these counties have a plan to cut back on their use of non-renewable energy?
The Expert answers:
The most?
USA
China
and probably Brazil
China uses very little reneawble energy, Brazil fuels all their cars with ethanol made from sugarcane, so they’d probably have the most, the USA would be in the middle
Countries that use the least would be small, poor, sparsely populated countries, Bhutan is probably one of them
Laura asks…
is this saying appropriate for a renewable energy poster?
I’m drawing a poster for a contest, and it’s promoting the use of renewable energy. I have the title coming across the top as “Cleaner Energy for a Cleaner World“, and I would like to have this sentence in the middle of the page:
“Using renewable energy sources can lower expenditures, create jobs and a healthier environment for all.”
I’m not sure about the “lower expenditures”, what can I replace that with? I just want to make sure that I’m not saying an incorrect phrase haha. Thanks!!
The Expert answers:
I would replace this with “improve energy security and cut our dependence on foreign oil”.

Donna asks…
Can renewable energy provide the world with all its energy needs and if so then when?
This is including the increase of energy requirements in the future which is meant to increase by 80% by 2030. If you could provide supporting links that would be great.
The Expert answers:
That’s a loaded question… We first need to reduce our requirements for more energy. Conservation and efficient use should go hand in hand with developing alternative, renewable clean energy. For example solar and wind energy have their own environmental impacts(though not as negative as fossil fuels), if environmental concerns are assumed in your question. Otherwise just go nuclear if your only concern is energy sources and not its environmental impact.
Sandra asks…
How does renewable energy help in third world countries, and how does it improve there quality of life?
The Expert answers:
One example I can think of is a solar oven. People can cook without having to chop down all the trees in the area or wander to look for wood. The solar oven also doesn’t create smoke pollution.
