- checking grammar Hello community I need to present a short exposition (5 minutes) of an argumentative essay about solar energy. Can you help me, check it? please Good evening Teacher, good evening guys I’m going to talk about my argumentative essay The main topic of my essay is solar energy If you ask me, why do I want to talk about that topic? The answer is simple: Solar energy is the solution to climate change In my opinion, it's time to stop using fossil fuels. Fossil fuels are the planet's number one enemy: air pollution, health problems, climate change Fossil fuels cause these problems. In recent years engineering has been developing new solar technology. For example, Airplanes powered by solar energy, solar cars and solar panels that supply homes of electricity. These advances are important in demonstrating that solar energy can solve the problem of climate change. but there is still a lot of work to be done. Therefore, the biggest challenge that engineers face today is to position solar energy as the energy of the future above fossil fuels. These are the 3 reasons that support my thesis First reason: the days of life of fossil fuels are numbered. According to a study from the International Energy Agency, the oil supply will run out in 53 years, natural gas in 54 years, and coal in 110 years. Second reason: the problem with solar energy storage is being solved For example thanks to the Tesla Powerwall battery you can store the sun's energy during the day and use it when you need it. Third reason: the costs of solar energy have decreased In India for example, the price of kilowatt per hour of solar energy equals the price of traditional electricity My conclusion is: if engineers can make solar better technology, reducing their costs, solar energy will be consolidated as the main source of energy on the planet, and fossil fuels will be eliminated as an energy tool. I elaborated my essay following the hamburger model. Firstly, I answered the question what is the biggest challenge that engineers face today? My answer is the essay thesis Secondly, I established my arguments and examples of reliable sources to support the ideas. Finally I elaborated my conclusion The sources that I consulted to elaborate my essay were: international Energy agency, world health organization, U.S Department of energy and this famous newspaper, New York Times.

- Energy solar I have written 2 paragraphs about solar energy Can you help me, check it? please Some people claim that using solar energy is not viable because of its dispersal and storage problems. This is completely false, currently, there are rechargeable batteries such as Tesla Powerwall’s that can store excess energy generated during the day and make it available when needed. For example, in the city of Phoenix, Arizona, the hottest city in the USA, today half a million people heat up and light up at night, when there is no sun, with the energy captured from the sun during the day. On the other hand, there are governments that seem to disagree with the use of solar energy. In the USA, for example, President Donald Trump's administration has raised taxes on solar panel imports, removed his country from the Paris climate change agreement and proposed reviving the US coal industry. Such measures only show that private interests take precedence over the care of the planet. In conclusion, if engineering succeeds in improving current solar technology, reducing their costs and providing efficient ways to use electricity to create storable fuel, solar power will be consolidated as the main source of energy on the planet and fossil fuels will be eliminated as an energy tool. Evidently, the way of life will be different, but perhaps it was not different 100 years ago when people still washed in the rivers and cooked with firewood. The people of that time accepted the new technologies: They rode trains, got on planes, put electricity in their houses, and everything else we have. They were made to believe that oil lamps could not compete with electric light, now we are made to believe that solar energy is not competitive with that of oil. If before we were able to change to a much better world, today we can do exactly the same.May 8, 201920
- production costs of solar energy Hello community Can you help me check it? Please Another factor to consider is the decrease in solar energy production costs with respect to previous years. Believing that the great problem of solar energy is its cost, is not valid. Solar energy technology advances at the time it becomes cheaper. According to the U.S. Department of Energy, costs fell 61% from 2008 to 2016, it is estimated that by 2020 the reduction will be half. In India, for example, a country that bets heavily on solar energy reached an unprecedented record, the price of Kilowatt per hour of solar energy reached 0.037 dollars equaling the price of traditional electricity. From my point of view, if engineering manages to develop materials that would lower production costs even more, what happened in India can be expanded to other countries so the energy transition could be given faster.May 7, 201950
- fossil fuels and solar energy. Hello community I've written a paragraph about fossil fuels and solar energy. Can you help me, check it? First of all, the days of the life of fossil fuels are numbered. According to a study carried out in 2017 by the international energy agency, it is predicted that with current reserves and production rates, oil will run out in 53 years, natural gas in 54, and coal in 110. It means we have fossil fuels to spend only a few decades. In addition, fossil fuels cause serious environmental and public health problems. The global health organization in a report published last year revealed that 9 out of 10 people worldwide breathe polluted air, and according to the organization, pollution is responsible for 7 million deaths every year. "It is unacceptable that over 3 billion people — most of them women and children — are still breathing deadly smoke every day from using polluting stoves and fuels in their homes" said WHO Director-General Tedros Adhanom Ghebreyesus. According to the WHO, air pollution is a critical risk factor in causing strokes, lung cancer, heart disease and respiratory infections like pneumonia. Against this backdrop, solar energy has certain advantages, it is an infinite source of energy, friendly to the environment and does not generate health problems. This makes her a number one candidate to be the energy of the future.May 7, 201930
- argumentative essay about the challenge of engineering with solar energy. I have written the first paragraph of an argumentative essay about the challenge of engineering with solar energy. Can you help me check it? Energy solar: a challenge for Engineering. The energy of the future is power solar. Airplanes powered by solar energy, cars equipped with rechargeable solar batteries, solar cells that provide electricity to the home are just some technological advances that engineering has been working in recent years. Engineers driven by the need to reduce the effects of global warming caused by fossil fuels have detected in solar energy an alternative solution to the problem. The use of renewable energy sources is a trend that is gaining ground, but there is still a lot of work to be done. Therefore, the biggest challenge that engineer faces today is to consolidate solar energy as the energy of the future.May 6, 201950
