Choose Green Home Remodeling and Let the Sun’s Energy Power Your Home

When considering a green home remodeling project, think of the sun. Now is a perfect time to consider switching to a renewable energy source such as solar power. Many homeowners don’t consider solar because they think it too expensive, unreliable, or complicated. However, solar panels have improved greatly in the last 20 years. They are smaller, more efficient and reliable, less expensive, and easier to obtain.
Solar energy creates no pollution and it’s free. While solar panels themselves are not free, they’re a very effective long-term investment. A variety of local, federal and state tax credits and incentives can cut the expense by as much as 50 percent. If you generate more power than your home uses, you can try selling the extra power to your local utility. You can also rent your solar panels, reducing your initial cost, and letting you pay for the rental from energy savings.
Many homeowners erroneously believe that solar power will provide reduced power at certain times or will require expensive batteries. Solar systems can create power on cloudy days, although they generate more on sunny days. Because most solar panels are tied to the electrical grid, a process called net metering allows you to build up credit during the day – when your system is generating more power than you need – and draw on that credit at night. If your home is too isolated for a grid connection, you may want to consider a generator or a battery back up.
Before you sign on for solar there are a couple of considerations. First, check your utility bills; if they are already low for your area, solar panels might not be a good investment. Next, see how much sun hits your roof every day. If your roof is shaded for much of the day, you might not be a good candidate or you may need to trim some trees. Finally, see if your roof has a southern exposure. Other exposures work, but they may be somewhat less efficient or more expensive.
Good installers can evaluate your home’s potential for solar power and make estimates for costs. As with any green home improvement project, it pays to get bids from a number of contractors. Choose a company that is experienced and licensed.

Can I Really Power My Home With Wind Energy?

The Federal Tax Credits currently available in the US for upgrades for residential energy efficiency are significant enough to have many people thinking about energy efficiency remodeling. There is much discussion around the cost benefits of installing solar energy systems and even geothermal heat pump systems. But many homeowners are still asking, “Can I really power my home with wind energy?” The answer is “Yes!”
When most of us think about wind energy, we flash on images of huge turbines lined up in mid-western or off-shore wind farms. We see pictures of turbines 150 yards in diameter that sit 3000 feet above sea level. But wind technology is advancing daily. In fact, turbine design is advancing so fast that some of the wind-energy web sites are having difficulty keeping up! 
 
Many farms and other residential and industrial facilities in rural areas have been using wind turbines for years to provide all power for their needs. But as interest in powering homes with wind energy grows, new technologies are producing quieter, more attractive, turbines that can be effective at lower elevations. In fact, there are new turbine designs that can be incorporated into landscaping design around homes. 
 
The economics of wind power depend on where you live, how much wind is available on a continuous basis at what elevation, and whether you plan to invest in batteries to store excess energy. The economics of wind power also depend on whether you plan to install a stand-alone system to provide all of your energy needs or you plan to connect to the electric grid serving your area and use a wind energy system to generate power that you supply to the electric company in exchange for free energy. Either way, a small wind system could provide all of the power your home needs with wind energy. 
 
You can now purchase a wind generator from and from several other online retailers. You can also purchase complete wind systems from the manufacturer. At the very least, you can do your homework online before you start talking with a local contractor. Most states currently require that wind power systems be professionally installed by certified contractors. Before you purchase any equipment from any source, you should discuss your options and what kind of systems are working for other homeowners in your area with your contractor.
 
Choices of turbines are generally based on the amount of wind power generated by the system. This is measured in kilowatts. For example, a 1.2kW turbine produces 1200 watts. A turbine of this size installed where there is an average wind speed of 12 mph will produce about 2000 kilowatt hours of electricity per year. The cost of a wind system usually ranges from $3,000 to $5,000 per kilowatt connected to the grid. The cost could be lower for an independent system not connected to the grid. Turbines are expected to last about 20 years. 
 
In most cases, the installation cost for a 10 kilowatt residential system will be about $35,000 to $40,000. In an energy efficient home, this system could meet all energy needs, eliminating the electric bill. The amount of time needed to recover the cost would depend on current average monthly electric bill (e.g., a home using $200 of electricity per month, would recover $2,400 of the cost each year) and the available purchase incentives. The incentives would begin with the current Federal Income Tax Credit of 30% of the cost of equipment and installation or $10,500 – $12,000. Many states also offer such incentives as investment tax credits, sales tax reductions, property tax reductions, and financing assistance. Many utility companies also offer a variety of incentives, including net metering, to wind system installation.
 
In short, it is entirely possible to completely meet the energy needs of an energy efficient home with a wind power system that could be expected to pay for itself in as little as 10 to 15 years.

Ten Myths About Geothermal Heating And Cooling The Nice Energy Challenge Weblog

air+and+heating+systemsIt allows for the addition of air-con and heating in properties without ductwork, and with the least quantity of disruption to the interior house. A ductless mini break up air conditioner system is similar to a central system in that the compressor is exterior, eliminating the noise related to wall-sort units. Some areas have low cost electric energy, making electrical heating economically sensible. That is how geothermal heating and cooling techniques can get monetary savings on an ongoing foundation. Barely later, in 1716, got here the first use of water in Sweden to distribute heating in buildings.

In the subsequent Matter, I’ll continue explaining other configurations of cenetreliazed air conditoining techniques ; Centralized Fluid Based mostly Hydronic Systems & Combined (Hybrid) Water and Air Methods. Notably if you already have ductwork in place or for those who’re choosing a heating system for a new development home, it may make a variety of sense to opt for some type of compelled air heating.

Fan coil models might be in cased or uncased configurations, vertical or horizontal and with or with out fresh air inlet. The three main methods of mechanical cooling are fans, evaporative coolers and air conditioners. The diagrams and descriptions in this part outline central heating and air conditioning, forced-air furnaces, as well as radiant heating techniques.

To put in a one to four room system begins with the creation of an opening within the exterior wall of the house, and the working of refrigerant and electrical strains into the rooms in which the wall or ceiling air handlers 1 might be put in. The glossy, ductless air indoor unit mounts discreetly within the space, and a pair of small refrigerant strains plus energy and management wiring, connect it to the out of doors unit by way of a small three-inch opening within the wall.

Recent air is drawn into the building through the consumption louver, mixed with return air, heated or cooled to a managed temperature, circulated around the building and offered to the occupied house. In contrast to conventional heating and cooling methods, mini-splits offer an assortment of great options aimed at boosting comfort. Typically known as split programs, multi-break up programs, or split-ductless methods , ductless cooling and heating presents dwelling and business house owners a cost-effective technique to exchange inefficient window items, area heaters and electrical baseboard heaters.
