Can renewable energy change the world?
yes
Why was hydro power invented?
Hydro power was invented because a clean renewable energy source was needed. The world's supply of coal and oil are being used up, and those resources are not renewable.
What are the energy issues you are facing in the world that would make a solar cooker a viable option for many people?
The energy issues we are facing in the world that would make a solar cooker a viable option for many people include the lack of renewable resources that are available. Wind power and wave power are not as readily available as solar power.
What is the process of operation of a hydroelectric power plant?
Worldwide, hydropower plants produce about 24 percent of the world's electricity and supply more than 1 billion people with power. The world's hydropower plants output a combined total of 675,000 megawatts, the energy equivalent of 3.6 billion barrels of oil, according to the National Renewable Energy Laboratory. There are more than 2,000 hydropower plants operating in the United States, making hydropower the country's largest renewable energy source.In this article, we'll take a look at how falling water creates energy and learn about the hydrologic cycle that creates the water flow essential for hydropower. You will also get a glimpse at one unique application of hydropower that may affect your daily life.
Is silica a renewable resource?
No because, Like fossil fuels, silica (found in the world's sands and quartz) is a non-renewable, finite resource. However, silica is a far more plentiful resource.
Is solar energy the energy of tomorrow?
Yes, because all renewable energy in the world is in one way or another driven by solar energy. It is differnet from parts of the world wether one should focus on solar energy as the renewable energy source. For example, in Africa that can be useful, but in countries like Britain, it can be better with for example tide energy.
Can renewable energy change the world?

What is efficient about renewable energy?
I think, at this moment very important of renewable energy because recently ends of fossil fuel in the world and other non renewable energy sources is not available in the world. non renewable energy is more complex system and more costly. but renewable energy is endless of input energy or initial energy, it reproduce itself, it's whole life me and your continuously give the energy sources e.g: sun, wind,water(Tidal). it's also important, it's power produced without pollution.
What are two reasons for renewable sources of energy been better than non renewable sources of energy?
