Wind and solar power is the only way we can go if we want to save this world.
Remember the sun provide all the power the world need for a year, in just in one hour.
We need to start using this, and stop using so much fosil-fuel.
We don’t need oil to live ,but we need our planet.
Wind is also something we should start using more.
It is always there. Day or night.
We just need to find the best locations for a wind-mill park.
The combination of wind and sun will give us all the green power we need.
The problem is that goverments in oil producing contries dont want this.
They are afraid they lose some money.
If you can produce your own electricity the government can not control you
by raising the prices.
Green Roofs or Solar Roofs ?Do you want to contribute to our earth but don’t know how? Global maiwrng and the urban heat island effect are making inroads into our homes. This is a serious issue, and we must also have a positive attitude toward mediating this situation.Suppose that you are not a boss of an enterprise; therefore, you are powerless to decide how to reduce air pollution nor recycle resources. Don’t be discouraged! You can still influence others and help preserve the earth by supporting the idea of green design. Green design is an internationalidea that has been discussed for many years, and was promoted in the 1992 Leaders Summit Meeting in Brazil. It is called ecological building in Japan and sustainable building in Europe. Home green design is an affordable way to save energy. Two methods of saving energy are the green roof and a roof covered by solar panels. Though each of these two methods have their own advantages and drawbacks regarding expense, working conditions, and function, green roofs are a more effective way to save energy.Expense is a very important thing taken into consideration when deciding between green roofs and solar panels. For a 100 sq foot roof, you need about $25,000 to install solar panels on your rooftop. The system works at least 25 years. However, maintenance of the solar panels will cost $1,000 per year, putting its worthiness into question. Its worthiness depends on your personal electricity usage. You would save a small amount of money if you are living with a big family, but a fact that should be taken into consideration is that the value of money between now and the future fluctuates. Otherwise, you still need to pay the upkeep of the system every year and the charge of basic power to keep it working. Green roofs are priced $1,500 for the same area without the need for maintenance. Then, all you need is a waterproof rooftop, a layer of soil, and a bag of seeds. The idea of Green Roof is much cheaper obviously and has lower maintenance costs than solar panels.An additional factor to consider are the working conditions of each method. Before you choose one of them, you need to consider the weather in your area. Solar panels, as the name hints, is a system that needs sunlight to function. Green roofs need adequate rain to support growth as well as sunlight. Comparing the two systems’ working requirements, solar panels need less than green roofs. Though solar panels still work on cloudy days, they will not maintain the same efficiency as they would on sunny days, though the amount of energy provided may be enough depending on your needs. Unfortunately, solar panels are not ideal for windy areas because they might be damaged by flying debris. Though the solar panels and green roofs are nearly equal in regards to working conditions, green roofs are slightly advantageous in that they are working 24 hours a day.Lastly, solar panels and green roofs have slightly differing functions. In theory, solar panels basically reduce your energy consumption. What would be powered with solar electricity are the things such as the refrigerator, the computers, the TVs and the airconditioning, etc. Sounds great, but solar panels efficiency averages only 20% to 40%. Solar panels absorb sunlight and convert its energy to a type of power we can use for electronics. The system loses much energy during theconversion process, and will not be able to power appliances unless sufficient amounts of sunlight is absorbed. On the other hand, green roofs filter rain and air pollutants in addition to keeping the house warmer in winter and cooler in summer. Sometimes it caneven provide a habitat for birds and some small animals.Choosing between solar panels and green roofs is a fascinating question. Though each system has its own benefits, green roofs are more advantageous to the average person. Solar panels are presently an underdeveloped technology especially concerning energy conversion and are more costly than green roofs. Protecting the environment is an important thing and we must work to solve the problems threatening it.I was going to add a few notes here and there, but the answer was too long. Try to make an original title, and not say I am going to because it’s obvious. Also, if I changed the meanings of some parts (some parts were ambiguous), feel free to ignore the change.Hope I helped.
I am considering siarttng a solar/wind energy business. I would like to know how many people would really consider installing solar panels and/or a wind generator on their home or business. If a complete system is too costly, would you consider a battery back-up system to run essential items in you home or business for when the power drops out? This would consist of 4-12 batteries, a couple of solar panels and/or a wind generator. This would operate items such as lights, well pump, refrigerator, radio or TV, telephones, and computers. Would you consider siarttng a small solar array (4-6 panels) and adding panels to it when you have extra money to spend on them?Please give me your feedback on what you think of GREEN energy and if you think it is the future or just a fad.Good answers so far. In response to f100_supersabre, A 4 battery system is not much. It all depends on what you will operate and how long. The more batteries the better. About the telephone, yes they are powered by the telephone line but businesses usually have multiple lines with a switching station that needs electricity to operate. Most homes now only have cordless phones which require electricity. If you keep a corded phone in your home this would be a non factor. When it comes to the size panels and wind generator that is relevant to your power consumption. What might be good for your house may be too big or too small for your neighbor.Keep the answers coming.
