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.

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.
What is an energy source that can't be used up by humans?
Renewable energy sources such as solar, wind, and hydropower are considered to be inexhaustible as they are naturally replenished. These sources of energy do not deplete over time and can be utilized indefinitely without running out.
Do humans have renewable energy?
Yes
Conclusion to the extra use of non-renewable sources of energy?
Relying heavily on non-renewable sources of energy leads to environmental degradation, resource depletion, and contributes to climate change. Transitioning to renewable sources of energy like solar, wind, and hydro power is crucial for a sustainable future. Reducing dependence on non-renewables will help preserve the environment and ensure a stable energy supply for future generations.
What kind of energy do humans mostly use?
Humans mostly use electrical energy generated from various sources such as fossil fuels (coal, oil, natural gas), nuclear power, and renewable sources (solar, wind, hydropower). This energy is used for lighting, heating, transportation, and powering electronic devices.
What are the types of energies used by man?
Humans utilize various types of energy, primarily categorized into renewable and non-renewable sources. Renewable energy includes solar, wind, hydroelectric, geothermal, and biomass, which are sustainable and have a lower environmental impact. Non-renewable energy sources include fossil fuels like coal, oil, and natural gas, as well as nuclear energy, which, while efficient, can contribute to environmental degradation and resource depletion. The transition towards more sustainable energy practices is a significant focus in addressing climate change and promoting energy security.
What is a resource that humans use to produce energy called?
A resource that humans use to produce energy is called a fuel. This can include sources like coal, natural gas, oil, or renewable resources like solar, wind, and hydro power.
Which renewable energy source was first used by humans?
The first renewable energy source used by humans was likely wood, as it was used for heating and cooking thousands of years ago.
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.
Why should humans in investigate alternative energy sources?
Humans should investigate alternative energy sources to reduce dependence on fossil fuels, which contribute to climate change and environmental degradation. Exploring renewable options like solar, wind, and hydroelectric energy can lead to sustainable energy solutions that are cleaner and more resilient. Additionally, diversifying energy sources can enhance energy security and create economic opportunities in emerging industries. Transitioning to alternative energy is essential for a sustainable future and for protecting the planet for future generations.
Which type of energy do humans as a society use most?
Humans as a society primarily use fossil fuels as the main source of energy, such as oil, coal, and natural gas. These energy sources are used for electricity generation, transportation, and heating, among other applications. However, there is a growing shift towards renewable energy sources like solar, wind, and hydropower to reduce reliance on fossil fuels.
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.
