Renewable energy

What is renewable energy?
Renewable energy is produced using natural resources that constantly replaced and never run out.
Types of renewable energy
Sunlight, wind, rain, tides and geothermal heat are all the examples of renewable energy.
Benefits of renewable energy.
One of the benefits of renewable energy is that it is naturally occurring so does not harm the environment and also that it doesn’t run out. Another benefit is that it is generally it is cheaper to produce renewable energy because created by the environment.
Renewable energy has a great impact in public health because unlike fossil fuels like coal it does not pollute the environment and cause illness in people. It is called clean energy. Wind, solar

Renewable energy also relies on weather conditions such as sunlight, rain, wind and waves which is beyond our control.
Renewable energy is a source of energy that does not consume the finite resources of the earth and can be easily and quickly replinished. Science Competition 2017

Introduction:
One of the disadvantages of renewable energy is that you are unable to control the weather. For example, if you are using a solar source of renewable energy, you rely on the sun being out.
My science project is designed to provide a more efficient way of capturing and storing renewable energy by using to natural energy sources, wind and solar.
My design is a windmill with a solar panel and battery storage.
Hypothesis:
When the wind is blowing, the windmill will be moving and creating renewable energy. If the wind stops and then sun is out, the windmill will continue to produce renewable energy by using the solar panel and motor that will spin the windmill.
Renewable energy: energy in which comes from natural resources that are naturally replenished, such as sunlight, wind, rain, tides, and geothermal heat (Bhatia, 2014). This essay is focused on the main three renewable energies, wind, sunlight, and water. Renewable resources are well on the way to out rule the fossil fuel industry because of the diminishing amount of fossil fuels left in the world and increase of renewable resource use, the damage fossil fuels do to the environment, and the various positive aspects that renewable resources bring.
Renewable energy is energy from a source that is not depleted when it is used.
Renewables are better environmentally than any other power source under specific circumstances. The two most touted renewable energy sources are wind power and solar power. The specific circumstances in which they are better are when the wind is blowing and the sun is shining. Unfortunately, neither the wind nor the sun can be guaranteed to function for any specific date or time. The sun can only be guaranteed not to shine for approximately twelve hours a day and wind has no guarantees at all. Also, technology is not advanced enough to adequately harness the power provided by the sun and wind when they are available. It would take five hundred times the amount of land to build a solar plant with the same output as a nuclear plant (Oliver Hospers 24-25).
According to http://www.conserve-energy-future.com/advantages-and-disadvantages-of-renewable-energy.php, “In the event of weather that doesn’t produce these kinds of climate conditions renewable energy sources lack the capacity to make energy. Since it may be difficult the generate the necessary energy due to the unpredictable weather patterns, we may need to reduce the amount of energy we use”. There are different types of renewable energy but the most popular types are solar and wind power. Solar power works by the solar panels consuming the heat and the rays from the sun that can be transformed into energy.Wind power works by the amount of wind which then turns the propellers on the wind turbines which produces
Another cons of renewable energy is that to produce large amount of energy, large amount of solar panels and wind farms have to be set up. For this, large areas of land is needed to produce such massive amount of energy on large scale.
Renewable energy has the power to solve climate change, nuclear proliferation, energy insecurity, and energy poverty.
Each source of renewable energy has its own characteristics but hey all serve the same purpose in producing green energy. Throughout this research paper, I will describe each one of them and describe the environmental and economical benefits associated with the production of green energy.
Solar power is a renewable energy source because humans are not using any of the earth’s resources and because the sun will never run out or be extinguished. Each day you will generate electricity from the sun
“Renewable resources have a high development cost it costs lots of money to develop there stations in research and manufacturing the components needs so that they become successful.” Which is stated in the article of pros and cons of renewable resources. Renewable resources also do not produce in large quantities, so if we were to use renewable resources for energy we would have to reduce our energy consumption. Renewable resources are also vulnerable, almost all of the renewable resources are vulnerable to weather such as rain, snow, and cloudy days.
Wind energy is a renewable energy resource that is natural occurring with unlimited supply. The energy generated from wind is clean with little impact on wildlife and the environment. Technology such as wind turbines are used to capture the energy from wind. Compared to Solar energy, another renewable resource that uses the suns heat as energy, wind energy is less efficient. The amount of power collected from solar panels exceeds what is collected from turbines. Although solar energy are more efficient, it comes at a cost. Solar technologies are more expensive than wind turbines and
Renewable energy may seem like a daunting task, but the benefits to humanity could be incredible. Public uses of renewable energy range from transportation all the way to heating and cooling. Everything we use could become less explosive and less expensive. Cities with a high concentration of people could become safer and healthier places to live. Transportation could be converted to electricity dramatically, improving smog conditions. Global warming may or may not
Renewable energies have satisfactory EROEIs and they aren’t subject to depletion unlike non-renewable and nuclear energy sources. However renewable energy sources are far from producing enough energy to fulfil the world’s needs.
Converting to renewable energy sources would have a devastating environmental impact. In addition to solar panels, wind turbines and hydroelectric dams would make up the largest portion of renewable energy generation. Wind farms create hazards in their areas of operation. They consume up to 200 times as much land as gas-fired power plants (Langwith). If 25 percent of our nation’s energy came from wind, the turbines would kill more than a million birds each year (Langwith). Experts have been unable to find a solution to this problem.
The other benefit of renewable energy is that these energies have been found to be non-polluting and therefore halt global warming. This is very good news for us as a species because according to many simulations of the future,
Soon, planet Earth will run out of the resource that once was thought to be reliable. Earth is in great danger of self destructing if there is no backup plan. This is where renewable resources come in. Renewable resources are abundant and do not damage the environment, so they are a sustainable method to produce energy. The options for renewable energy are solar, wind, hydro, biomass, and geothermal.
