The photosynthetic procedure can be altered to make the reaction between CO2, H2O and light produce liquid hydrogen. Liquid hydrogen can be used in hydrogen-powered systems as a gasoline. Hydrogen fuel cells can also produce electricity, which could be used to power a lot of everyday things. The main reason why artificial photosynthesis would be so useful is because it creates fuel from natural resources, so it doesn’t harm the environment. When humans burn fossil fuels, we emit toxic gases into the atmosphere that harm earth and increase global warming.
Boli Monger Danny Bellinger English 1101, 60499 July 11, 2017 Compare and Contrast Solar energy is better than Coal In today’s world energy is one of the essential things that we all need in our daily life. We human being use energy for everything from doing simple work at home to doing big work, like sending astronauts into space. There are various sources of energy, among them, the healthiest and environmentally safe is solar energy. Solar energy is defined as a renewable form of power or heat which is naturally produced by the sun light. According to the Energy Information Administration (solar vs coal 2), 15 years ago, the electricity industry made a huge shift towards renewable sources of energy because of its cheap availability and increasing popularity.
“It’s carbon footprint is massive – try 241.85 tons of CO2.” Now let’s move on to solar power. For someone to build a fully functional nuclear power plant it would cost only a couple million dollars. According to The Union of Concerned scientists’ website it costs, “between $2 billion and $4 billion per unit.” When looking for how much it costs to make a solar panel we see that it’s significantly smaller than building than a nuclear power plant. According to Solar Power Authority’s website, each panel fully installed costs about, “A 5 kW system would cost around $25,000-$35,000”. But we then have to take into account the amount of energy produced by each one in a year.
(Fossil fuel power plants also generate electricity by first creating steam to drive a turbine.) The main applications of solar thermal energy at present are the pool heating, domestic water heating and space heating of the building. What Time Is It Songs - kids learning English To this end, the general practice is to use solar-dishes sensors with fixed orientation (position). When space heating is the main consideration, the highest efficiency with fixed flat-plate collector is achieved if it faces south and slopes at an angle to the horizon equal to the latitude plus 15 degrees. Solar energy Solar collectors fall into two general categories: nonconcentrating and
Solar energy is a natural renewable resource that has a huge potential because it can easily supply energy for the whole Earth and will never run out. The sun produces a huge amount of energy in light and heat form. It can be used by humans in several ways, for example in solar heating, photovoltaics, solar thermal energy, molten salt power plants and concentrator solar power technologies. Solar energy can either be used directly or indirectly by first turning it into electricity. Potential The amount of solar energy that is absorbed by the atmosphere is huge, about 3,850,000 exajoules (1 exajoule = 1018 joules) per year.
These panels trap the suns rays and convert them to energy that can be used instead of the traditional fossil fuels. Wind energy is collected using wind turbines that "collect and convert the kinetic energy that wind produces into electricity to help power the grid. "(Office of Energy Efficiency and Renewable Energy., n.d.). Wind energy is actually a byproduct of the sun, technically making both of the options I choose solar energy. Here is a picture of a wind turbine.
It acts as a blanket to keep our Earth warm and protected from the temperature in space. This is known as the greenhouse effect. The main cause of global warming is the large contribution of Carbon Dioxide (CO2) to the atmospheric layer. What causes the rise in carbon dioxide some may ask, is the burning of fossil fuel used to produce power and electricity, like oil, coal and natural gases. Every time these fossil fuels are burnt, more carbon dioxide is released into the atmosphere, resulting in the thickening of the greenhouse layer, making the Earth a lot warmer.
Also they are non-renewable sources of energy. Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves, and geothermal heat. It is the energy which is abundant in nature. The sun is the ultimate source of energy. Almost all the energy that we use eventually comes from the Sun.
1.1 Wind Energy System Wind is air in motion, it is due to uneven heating of earth surface by the sun rays. Since the earth surface consists of different types of land the water, it absorbs the sun heat at different rates. Wind energy is mainly used to generate electricity like earlier wind mills modern wind machines used blades to collect the winds Kinetic energy. 1.1.1 Advantages 1) The blades ere connect to shaft that turn on an electric generator to produce electricity. 2) Use of wind power to produce electricity on commercial scale has become the fastest growing energy technology.
Every single day, humans emit greenhouse gases into Earth’s atmosphere. These gases keep Earth in a life-supporting temperature of about 15 degrees Celsius, but too much of these gases can also eradicate life too. Since the Industrial Revolution, greenhouse gas emissions have increased. The excess of these gases now become the causes of life-threatening problems. Excess of greenhouse gases in the atmosphere is harmful to the environment because it causes global warming, increases the acidity of the ocean, and depletes the ozone layer.
