SOLAR ENERGY Karol Pakkas What is solar power? Solar power is energy that comes from the sun. The sunlight gives off energy as heat. Solar power is a renewable source of energy. How does solar power work? Solar panels are used to collect sunlight. Solar panels are made up of photovoltaic cells that convert the sunlight into energy. Why do we need it? How does it lead to better health? Solar power is source of clean energy. It does not produce pollution or greenhouse gases or carbon compounds. Solar power would be a lot safer for the environment and a lot better for the health of people. What would happen if we don't use solar power? If we don't start using solar power, we would use oil and coal. They produce pollution and will cause millions of people to suffer from respiratory related problems. The oil and coal will run out and people will have to resort to

Renewable energy Meriliin Lend Estonian University of Life Sciences Tartu 2013 Topics Renewable energy Solar energy Wind energy Hydroelectric power Geothermal energy Biomass energy Renewable energy Renewable energy comes from sources that naturally renew, or will not run out in our lifetimes. Includes sunlight, wind, water, geothermal heat and various forms of biomass. Renewable energy cannot be exhausted and is constantly renewed. Does not harm the environment. Saves money. Solar energy Solar energy is the technology used to harness the sun's energy and make it useable. Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year. Solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains in efficiency. Solar energy is inexhaustible. Noise free.
and also woods, groundwater, animals and so on, in other words it's everything that human hasn't created. These resources are also used in industry. We get natural resources from the environment. Many of them are essential for our survival while others are used for satisfying our wants. Renewable resources: Some natural resources can be reproduced within a few years or decades. These are called renewable resources. Solar radiation, wind and hydroelectricity, are perpetual resources that are in no danger of a lack of long-term availability. Some natural renewable resources such as geothermal power, fresh water, timber, and biomass must be carefully managed to avoid exceeding the worlds capability to displace them. Solar energy is the energy derived directly from the Sun. Along with nuclear energy, it is the most important source of energy on Earth. People usually use solar energy to produce
Green Energy Program paid for and brought to by -Anja Bananja -Franz the Manz - And Just Chadrick Overview- What is Green Energy? Different Types? What is sustainability? German Green Energy Cost and Efficiency Recycling What is Green Energy? -It is energy resources that are renewable -Can be naturally replenished -Clean, Safe and not harmful to the environment (aka mother earth) Types of Green Energy Green Energy going cute Solar Power · Is produced by using photovoltaic cells, which capture sunlight and turns that into energy. Problems ? -The sun has got to shine -The cost of solar panels and the systems range between $20k-40k -The light from the sun produces a very small amount of energy
Solar power What is solar power? Solar power is the energy, which is derived from solar radiation energy. Mainy used to heat and power production, but as well as natural lighting. Solar power released as a result of fusion reactions taking place in the sun. What is solar power? Päikeseenergia on energia, mis on saadud päikesekiirguse energiast. Põhiliselt kasutatakse seda soojuse ja elektri tootmiseks aga ka loomulikus valgustuses. Päikeseenergia vabaneb päikesel toimuvate termotuumareaktsioonide tulemusel. Using heat production production of electricity from solar energy Kasutamine: Soojuse tootmiseks (sh. tarbevee ja joogivee kütmiseks) kasutatakse päikesekütteseadmeid.
pollution that is much more radioactive and toxic than, for example, coal waste. But if we are looking at the facts, burning coal pollutes the Earth much more than nuclear power plants because more waste is generated. CO2, which is released from burning coal, is the main cause of global warming. Nuclear waste is collected and hidden in rocks or under ground, where it won't face the environment. However we shouldn't depend on nuclear energy as Uranium reserves are ending, especially when the world population is increasing and so is the demand for energy. There is Uranium in seawater, but getting it is too expensive. We can only depend on nuclear power for a few years or decades. On the other hand, we will always have wind and solar power. Right now, producing solar energy is quite expensive but as technology improves, we will hopefully be able to produce solar energy with lower costs. The world should use as much wind and solar
