disadvantages of wind energy
Ben Levanger asked With what seems the whole world focusing on energy wind has become increasingly popular among those looking to be energy efficient Alternative energy has been trying to get tracking for years and with the current global awareness at a all time high it is finally finding the footing its needed There are many advantages to wind power but with steep competition with the oil companies the benefits are almost always played down So what are some advantages and disadvantages of wind energy Advantages of wind energy Its renewable – the earth will never run out of wind and in some cases wind speeds have been increasing over the years making the case for wind energy even stronger Also with the increased wind existing wind factories will be producing at record rates Wind energy is clean there is no harmful effect on the surrounding eco system Wind turbines are someone expensive to build but once they are installed and operational there is no negative effects Wind energy is extremely basic – unlike nuclear power which is very complicated wind energy is almost crude in design when compared to other complex power system Costs – one the wind turbines
geothermal power pros and cons
Geothermal energy could be a buzz term gaining ground these days as we try for a lot of renewable resources which will help us generate electricity and ultimately have a healthier world The literal that means of the word geothermal springs from geo or earth and thermal or heat In alternative words geothermal energy originates from the earth or within the planet to be precise A renewable natural resource at our disposal what could be wrong with that And if there is any draw back will it outweigh the positive To answer these questions it is important to examine the pros and cons closely and weigh every against our capabilities and also the long-term benefits Execs of Geothermal Power Direct use of geothermal energy Since ancient times folks have used geothermal power directly for purposes of taking baths getting ready meals and heating homes or buildings These days heating buildings is the most common direct use of the energy and it’s accomplished through use of district heating systems These systems pipe hot water into buildings from the surface of the earth and are accessible for immediate use Low emissions The most important drawback we tend to’ve experienced with burning fuels
CLEAR EDGE PRICE
Fuel cells and fuel cell technology has been a big buzz now for the last couple years with lots of talk and plans for cars that run on them and so on But it has seemed to be very much a thing of the future and not of today in terms of consumer use of fuel cells for power generation But along comes a company to my attention of late that seems to be proving that wrong Clear Edge Power is advertising a hydrogen fuel cell power system for home and business use now not next year or beyond They have built a system that consists of a box about the size of a an air conditioning unit that houses their hydrogen fuel cell technology The system runs on natural gas which is converted into power using their proprietary fuel cell technology From the Clear Edge site ClearEdge Power offers a solution for high utility bills Begin saving money and energy with a single compact home fuel cell system You can depend on the ClearEdge for electricity heat and clear environmental benefits Cost efficient and reliable our unit is eligible for utility rebates and government incentives In addition the unit
how we use wind
As oil prices continue to explode tag alternative energy tag is getting a close look in the United States Here is a guide to tag wind energy tag in the USA One of the worlds fastest growing types of tag renewable energy sources tag is wind energy While most of the Earth is still reliant on different types of fossil fuels such as oil natural gas and coal for their energy supply many countries are trying to come up with alternative methods of obtaining energy Much of Europe has begun to build and use wind farms which are groupings of wind turbines that harness the energy of the wind in order to create energy and electricity Also involved in using wind energy USA has started to build their own wind farms tag Wind turbines tag are the individual components of wind farms and they are machinery composed of several main parts The first part is the rotor also known as the blades or the propeller and this is the part of the turbine that actually collects the wind energy and converts it into drive energy which then turns a shaft This shaft actually creates the energy that is then stored
google solar mirrors
Google has developed a prototype for a new mirror technology that could cut by half the cost of building a solar thermal plant the company’s green energy czar said on Friday Bill Weihl said that if development and testing go well he could see the product being ready in one to three years Things have progressed Weihl said in an interview We have an internal prototype Google has been looking at unusual materials for the mirror’s reflective surface and the substrate on which the mirror is mounted In solar thermal technology the sun’s energy is used to heat a substance that produces steam to run a turbine Mirrors focus the sun’s rays on the heated substance The Internet search engine company which has been investing in companies and doing research of its own to produce affordable renewable energy wants to cut the cost of making heliostats the fields of mirrors that track the sun There is a decent chance that in a small number of years we could have a -X reduction in cost he said Global companies are increasingly investing in green technology as the world grapples with global warming and governments strive to implement regulations that could limit
how much money does a solar panel save
No doubt you ve heard plenty about solar power but always thought it was too overpriced aside from minor uses in the now generalized garden lighting systems However with fuel prices climbing and solar cells becoming more reasonable adding solar power to your home is a brilliant lasting solution to high energy fees That isn t to tell they re economical prior rebates it normally takes or more years for a homeowner to make their investment in solar panels back That s much longer than the average person is willing to wait However several states now offer rebates so the final cost to the homeowner is much less than it use to be The rebates vary from state to state so it s impossible to tell how much of an affect they have overall There may also be federal incentives Solar panels are also steadily becoming more practical They generate more energy than they used to They need relatively little maintenance several of which you can be able to do yourself This contributes to make them highly cost efficient Solar energy isn t just for making electricity You can utilize it heat the water for your swimming pool or heat

POLYCARBONATE TROMBE WALL
widget ad unit- Indirect solar gain is one of three methods of passive solar heating in addition to isolated and direct gain When solar heat is collected in one area and transferred to another through the process of convection this is the indirect method Here’s a rundown of how it works As with most passive solar heating systems that don’t require the use of mechanical pumps or fans heat is invited indoors through a series of south-facing windows It is then absorbed through building materials with thermal mass or the natural capacity to absorb heat These materials include masonry walls or floors When placed in a container water can be even more effective than masonry or concrete in that it exchanges heat more quickly Water walls and roof ponds are examples of how water containers can be used for indirect solar gain These are described below Indirect solar gain uses the same strategies of heat absorption and convection as direct gain With direct gain systems however the living space itself acts as a solar collector Indirect solar gain places the heat collection system outside the living space such as between the south-facing windows and the living spaces A Trombe wall
