I want to work on renewable energy specifically building science and renewable energy stores like sell solar VP.solar thermal,hydro,batteries,pumps,etc… but in building science I have to install those products so what should I study,which career fit better?

electrical, cuz you would build them and i think that would be more fun to discover them then install them.

im doing a project for economics and i have to find out how economics & solar energy are tied together.

One has to consider the economics of using solar energy. If you want to install solar panels on the roof of your home, to produce electricity, you have to figure the costs involved.

Determine the cost of installing the panel and how long it is expected to last. Figure out how much electricity the panel will generate. Subtract that amount from your normal electric usage. Then figure out the savings over the life of the panel to see if the original expense is worth it or not.

If you live in northeastern Arizona and pay top dollar for electricity, it might pay to have solar panels. They have sunshine for 325 days a year.

I need to find a graph or date showing how much renewable energy the states of Australia uses, for example Darwin - 38%

Please help, been looking for ages

Hi Dear,
Fossil fuel products dominate Australian energy consumption and this will remain the situation for the foreseeable future. Australia’s dependence on fossil fuels is heightened by the fact that electricity is largely produced in coal-fired power stations; approximately 84% of electricity for Australian homes and industry comes from coal and 12% from renewables, mainly hydroelectricity.

ok i have found a few sites but they only say do this do that

they dont go into a lot of detail

i want one that gives me pictures/diagrams that shows me the simple steps along the way

also has to be easy to follow

thanks

Sunroom kits include the foundation material. the wall type. the doors and windows. the roofs. nuts and bolts. ball bearing wheels. panels and more. But before you opt for a kit. you should pay due attention to the flooring. insulation. roof system and wall material. Depending on these factors. you should make the purchase.

Selecting the right kit is essential to the sunroom of your dreams. Make sure that the size fits in all the furniture that you plan to place inside it. The size of the sunroom kits should be such that it compliments with the other rooms of the house. Moreover. it should not look as if it is an extra part of your house protruding outside. but it should appear as an integral part of the room beside which it is placed. The sunroom kit includes a number of items with the help of which even you can build your sunroom yourself. But. before purchasing sunroom kits. there are a few factors that you should consider.

Factors To Consider

One of the chief factors that you should keep at the back of your mind is the foundation of the sunroom. It should compile with the codes of the local building. Consider the climatic condition of your area. If in winter your area freezes. you need a foundation that goes around four feet deep below the frost line. This will ensure that the foundation of the sunroom does not contract and expand with the ground depending on the weather. If the area where you want to build the sunroom is a level land. it is best to place slabs to achieve concrete block foundation sunroom. If you can not do so. you will have to place a framed foundation and top it with footings that are concrete. The walls of the peripheral foundation should be of cement block or concrete.

The second factor to consider is the roof. Other than the roof of the prefabricated and all glass sunroom. the other ones generally have roofs that are framed with the aid of joists of varying spacing. sizes and insulation. You can also give skylight opening on the roofs. Make sure that the glass used in the sunroom complies with the safety codes of local buildings. Usually the windows of the roof and the set skylights meet the requirements of safety system.

The third factor to consider while purchasing the do it yourself sunroom kit is the type of wall that you will need. There are mainly three types - PVC. wood and aluminum. The PVC walls have good insulation and require very little maintenance. They are extremely economical and are available in varying colors. The walls of wood will lend an authentic look to the room and requires frequent maintenance. They are costlier than the PVC ones and can be easily painted or stained. The aluminum sunrooms are almost like the PVC ones but it does not have good insulation capability. They are less expensive than wood and more than the PVC ones.

Contents Of The Sunroom Kit

Some of the common contents of the sunroom kit include the foundation material. the wall material. the doors and windows. the roofs. nuts and bolts. ball bearing wheels. panels and more. They include roof glazing. wall glazing. selection of single or double pane types. doors that can be easily fit into any place. aluminum frames with hollow tubes in white and bronze color. They are provided with clear wall glazing to allow maximum amount of light transmission. The panels also have solar guard glazing for reducing heat by the maximum amount. The frames can be purchased according to the design that will suit your house best. The frames in white and bronze can give you a finish of baked enamel. They are available in various sizes. You can opt for the Cathedral type with vaulted ceilings and slanting roofs. The Conservatory style uses numerous glasses in the roof that merge into a single beam. You can give a classic touch to your room by styling it in Victorian and Georgian models. They can also be styled in Straight and Curved forms.
The Insulation Factor

A sunroom is built with the aim of providing round the year comfort. But to indulge in daily work or enjoy nature sitting in your sunroom. you need to make the glass enclosed area well insulated. In order to maximize insulation. you need to opt for an insulation material with a higher grade. As far as the studs are concerned. it is best to install larger size studs measuring 2X6 for enhanced insulation. Glazing is an important factor that controls the amount of heat and light in and out of your room. It is best to select a high performance material for glazing which can collect the natural light. block the rays of the sun and retain heat if you need it. Thus. make sure that before you purchase the sunroom kit. you have properly chalked out your requirements according to your budget on the size. style. color. walls. panels. and overall appearance of your sunroom. This simple task will provide you with an all season sunroom that will not only keep your comfortable and cozy. but will also enhance the overall appearance of your house.

As part of President George W. Bush’s Twenty in Ten initiative that aims to reduce gasoline consumption in the United States up to 20 percent in the next ten years, Bush Administration’s established the Alternative Fuel Standard (AFS) that will require companies including car manufacturer’s to utilize about 35 billion gallons of renewable and alternative fuels in 2017.

In regards with this, the U.S. Environmental Protection Agency (EPA) has also established the Renewable Fuel Standard (RFS), the country’s first ever comprehensive renewable fuel standard initiative. The RFS program was presented to the public during a recently press conference held last April 10, 2007 conducted by EPA and the National Highway Traffic Safety Administrator (NHTSA), along with the U.S. Department of Energy (DOE). Here is what the officials of the three government agencies have to say.

Energy Secretary Samuel Bodman:

“Increasing the use of renewable and alternative fuels to power our nation’s vehicles will help meet the President’s Twenty in Ten goal of reducing gasoline usage by 20 percent in ten years. The Administration’s sustained commitment to technology investment will bring a variety of alternative fuel sources to market and further reduce our nation’s dependence on foreign sources of energy.”

Meanwhile, Nicole R. Nason, Administrator of the National Highway Traffic Safety Administration said: “While we must look at increasing the availability of renewable and alternative fuels, we must also continue to improve the fuel efficiency of our passenger cars and light trucks. As a part of the President’s “20 in 10″ energy security plan, we need Congress to give the Secretary of Transportation the authority to reform the current passenger car fuel economy standard.”

The main objective of the RFS program is to promote the use of alternative fuels like ethanol and biodiesel that can be abundantly produced from agricultural crops found all over the U.S. including corn, soy beans, sugar cane, and other vegetables. Some of the initiatives, requirements, and other objectives of the RFS program include: motor vehicles sold in the U.S. by 2012 should run on about 7.5 billion gallons renewable fuel mixed with conventional fuel (like diesel or gasoline); reduce the utilization of petroleum-based fuel up to 3.9 billion gallons; reduce the harmful emissions and greenhouse gasses by 13.1 million metric tons by 2012; and reduce gasoline use by approximately 20 percent after the next ten years.

With the RFS program implemented, we might see a Jeep model with quality Jeep steering damper that runs on ethanol or biodiesel fuel.
