Is it possible for humans to get all their energy needs met by using only renewable sources?

I think the best answer to this question given was in the movie Gandhi when the actor playing the part of Gandhi, Ben Kingsley, was asked if India would ever attain the same standard of living as the people in England. To paraphrase his answer; he said, it would take more resources that the earth can supply for that to become a reality.
The other question that comes to my mind is: if we had an unlimited amount of energy, how many resources would we use up, and would it be possible that we use up all resources and have nothing left, even if we had the energy to continue, all the raw materials would be gone.
I think this is what happened to Easter Island. The original inhabitants overpopulated and then consumed and destroyed all the resources on their island, and then they all but a few died of starvation.

Conclusion to the extra use of non-renewable sources of energy?
If humans continue to use nonrenewable sources of energy, they will eventually run out of them. This means that eventually renewable energy sources will be the only energy source.
Why should humans have more hydroelectric power?
Humans need more electricity, regardless of source. Hydroelectric and other renewable sources of energy are preferred to energy produced from the burning of fossil fuels.
Where do humans get energy from?
There are many sources that humans can get their energy from. Humans typically get their energy from different food sources.
Do humans have renewable energy?
Yes
Is electricty nonrenewable?
Electricity itself cannot be considered renewable or nonrenewable--what matters is how that electricity is produced. Any resource that can be replenished by sustainable processes at a rate faster or equal to its use by humans can be considered renewable. Most of the electricity in the world is generated from nonrenewable fuel sources, such as coal, gasoline, natural gas, or other fossil fuels. Sources such as solar cells, windmills, hydroelectric dams, and geothermal power plants are considered renewable sources of electricity. Alcohol and biodiesel derived from renewable crops such as corn, sugarcane, and switch grass are also renewable sources of energy. Nuclear power plants, especially breeder-style reactors, may also be considered renewable sources of energy.
What is opportunity in renewable energy?
Because the world is depleting resources, engineers and scientists must find a way to recycle energy, that is, renewable. In the engineering field, we try our best to recycle our materials to maximize efficiency and to minimize cost. There are lots of potential sources of energy that we, humans can harness. One is gravitational force. Is it possible to harness useful energy from gravity alone? How about the motion of the Earth wtr to the Sun? These are the type questions that will shape how we harness energy, and answers to these questions will indeed benefit the human race.
How long will renewable energy last?
A sustainable resource means it will last for ever, or for as long as humans renew the source.
Why can't humans utilize energy sources?
Sure we can. We use energy, when we eat food.
Where do you get energy?
Every day humans use energy from a variety of sources. These sources included fossil fuels, wind, water, solar energy, nuclear energy, and geothermal energy. We even get energy from the foods we eat.

What are two sources of energy humans have access to?
Nuclear power, solar power.
Examples of renewable and nonrenewable energy?
renewable energy is energy which comes from natural resources such as sunlight,rain,tides,and geothermal heat,which are renewable 2008 ,about 19%of global energy consumtion came from renewables with 13% coming from traditional biomass
