Green energy
Green Technology, or environmently friendly technology, is technology that does not harm the environment, One reason green energy is superior to other engergy sources, is it does noto deplete the Earths natural resources. Another great reason to use green energy is it does not harm the environnment when making energy as much as other ways.
One of the best ways of creating green energy is through wind turbines.Wind turbines generate electricty through kinetic energy from the wind. When wind blows and catches on the blades they spin, which then makes a generater convert that into usable energy. Some places are making wind farms or, gaint arrays of wind trubines. These wind farms can make a small contributon to domestic power so we are using less unclean energy. Windmills are an endless source of energy that does not harm the environment.
Another technology we use today is solar power. Solar power is made from the suns rays and turned to energy.They take the speeding photons and convert them into an electtrical current. There are many people using solar power today. Some technologies are moving forward into more green products by making them solar powered. Countrys such as the US , Germany, Japan, and Spain are starting to be more and more solar powered. Solar energy is very cheap is well. If your electricty bill is high, solar power might be a good idea for you. They also cost very little to maintain. Aside from being cheap, solar engergy is abundent, it is an endless renewable resource.
Dams that have penstocks are also a very good souce of green energy. They basicly take the water from rivers and make them flow through a dam with penstocks to create energy. Water flows through the dam and spins a turbine in th...

...totype out there to prove them wrong. Most of the people who denied its possiblity were scientists investigating the hot nuclear fusion and most likely just wanted to have more funding for there projects. Even after all of them claimed that it was impossible, a remarkable amount of universities tried some of there own experiaments about the same thing they just said could not happon. I thought it was very interesting that all that happoned to the scientists Pons and Fleischmann because they chose to share it with the media before anyone else.

Some types of renewable energy sources include wind, solar, light, residue wood, soybeans, corn, sugarcane, rice, wheat, sorghum(milo), cotton, oats.(etc.). These sources show recycling or reusing items. There are so many types of resources in our environment. Many houses can be build out of these resources or recyclables. For example, rice hulls from milling industries can be made into electricity. Did you know that a 13-megawatt plant consumes approximately 600,000 pounds of rice hulls per day. By burning the hulls, a company called Agrilectric Power, located near Lake Charles, will take a liability and turn them into an
Solar power for instance is one of the most popular and easiest of all of the renewable energy sources to harness, especially for home and business uses. (Galbraith) For around the same ...
This source of energy cannot be used everywhere as it is obvious that not every part of the earth has enough consistent sunlight to sustain energy. This type of energy uses the direct sun to create the energy source. This source of energy helps the environment by generating clean and sustainable electricity without toxic pollution or global warming emissions. It tends to be more affordable. In 2011 a study was done and found that for equipment costs based on dollars per watt of electricity produced, were under $1 per watt
Human and technology can be considered to be inseparable now, however with the environmental condition that is getting worse and worse, technology seems to give a big impact on causing climate change. Still, studies suggest that we can turn technology to be an alternative to save the planet, which we called it as green technology. But in the other hand, technology is also bringing damage to the environment. So how does green technology work? And why is technology important in sustainable development?
Environmental friendly technology is rapid growing which focus on technical and scientific methods in order to benefit the earth.
Another important aspect of green architecture is the integration of energy efficient mechanical systems and conservation methods. Green buildings are designed to reduce or eliminate the dependence on fossil fuels. Additionally, green designs further help to minimize waste through the use of gray water recycling and other sustainable energy strategies. Grey water is conserved or saved to be recycled to water gardens.
...ination, hydrogen fuel and solar energy (World Economic Forum 2014). These are technologies that closely related to environmental and recourse preservation, which help the society switch to use renewable energy.
“Going Green” means to pursue knowledge and practices that can lead to more environmentally friendly and ecologically responsible decisions and lifestyle. It is a movement that many participate in to help improve the environment. Technology improves the “Going Green” movement since machines can help one save money, energy, and resources from being wasted (i.e. using hand dryers in replacement of having paper towels exchange periodically). There are many ways the society pursues “Going Green” such as going paperless, carpooling, and using solar panels. “Going Green” affects human behavior because it involves technological advancement, sometimes resulting in job loss.
First and foremost, unlike power plants that rely on combustion of fossil fuels, wind turbines do not produce atmospheric emissions. Strangely enough, wind is a form of solar energy. Winds are caused by the irregular heating of the atmosphere by the sun, the variations of the earth 's surface, and rotation of the earth. This wind flow, or kinetic energy, when "harvested" by modern wind turbines, can be used to generate electricity. There is an abundance of wind to meet our needs, “the potential of [the total] wind power [in the world] is… 20 times more than what the entire human population needs” (Maehlum). Currently, wind power is one of the lowest-priced renewable energy technologies available, costing between four and six cents per kilowatt-hour, depending upon the wind
Wind turbines are a great source of energy around the world. Wind turbines produce wind energy that can be used to power our homes. Wind turbines convert kinetic energy into mechanical power. Then this mechanical power gets generated into electricity. Wind turbines make energy by the wind turning the large blades, which spin a shaft that is connected to the large blades, which then operates the generator making electricity.
Understanding the environment would help you recognise the appropriate energy production system to use. Renewable energy is an alternative natural source to fossil fuels like sunlight, wind and geothermal heat. Wind turbines and photovoltaic panels are examples of energy production systems where the conditions of a particular environment has to be taken into account. If a building is located alongside or near
For example, in the United States appropriate technology is often link to the balance growth with the apprehension to the environment. With this concern in mind, they tense to be environmentally friendly by going “green” which mean using renewable energy. Renewable energy simply means that the source of the energy will always be available and can be replenished. Moving toward the use of renewable energy has been found to very beneficial in several ways. Some of the ways in which renewable energy is beneficial are it is cost-effective, it helps to improve the energy in our homes, and could cut the nation’s energy use up to about two-third within a year. Renewable energy industries generate energy using resources such as the wind, water, and the organic matter....
Green technology is the technology whose main aim is reduce the impact of human activities on the environment. In other words the target of green technology is to consume less natural resources, reduce the emission, produce goods with energy efficiency, take care of health and safety issues and reuse and recycle the goods after their usage.
Wind is a form of solar energy. The term wind energy describes the process by which the wind is used to generate electricity or mechanical power. Wind turbines convert mechanical energy from the wind into electrical power. Wind turbines usually have three main parts. There are blades that connect to a central hub, a box behind the blades that contains the generator, and a long stem that connects to the ground. The way how it works is that the wind turns the blades, which spins a shaft that connects to a generator making electricity. After the electricity is produced it is sent through transmission lines to a substation that is sent to business and homes. For the sake of our planet, we must promote a renewable energy economy. Wind power can be a foundation of that sustainable energy future because it provides jobs in states that are building wind turbines, is a renewable energy source, and does not damage our environment. The environment will not be damaged by the pollution, the natural resources will not be used up, and there won’t be generating of hazardous wastes. Welcoming wind energy today will lay the foundation for a healthy tomorrow that will affect everyone in the United States. There are obstacles and challenges that will make it more difficult, but the environmental impact is well worth it to invest more money into wind energy.
Well, eco friendly products are considered anything that doesn 't harm the environment and that means from start to finish. In order to be considered a green product, the item must be eco friendly from the manufacturing,
