Custom Home Builders Vaincrease Energy Efficiency Of My Home

Custom Home Builders VA:What can I do to increase the energy efficiency of my current home?

by: www.CustomHomeBuildersVA.com

Most advisers agree that energy prices are going to continue to go up. If you look at the possibility of further devaluation of the dollar combined with the possibility of draconian energy legislation, the opportunity of extraordinary escalation of energy prices exists.

Many Americans are living in homes larger than they need. Homes that were built for size rather than quality.

In my opinion, getting prepared for high energy costs is a critical component of any preparedness strategy.

First do all the conventional things to make your home as energy efficient as possible.

Add insulation, upgrade windows and doors (while you are doing this it is an excellent opportunity to upgrade your security), change light bulbs, upgrade appliances, install water heater blankets. If the plumbing pipes have relatively short runs it is very likely that a propane fired tank-less water heater would make sense.

Secondly, consider your heating system. This is an intensive area of energy for many homes.

We recommend wood-fired outdoor boilers where feasible. These units circulate hot water and can be used for many heating applications including home heat, domestic hot water, greenhouse radiant heat and swimming pools, to name a few.

If you have a heat pump, a propane furnace installed with the heat pump is a very good combination. This allows for an energy efficient propane furnace to do the heating when the heat pump is out of its operating range. While there are very efficient and comfortable heat pumps, the back-up heating strips on heat pumps are very energy intensive. Propane is still primarily produced in the United States.

Also, we have had very good experiences with geo-thermal. While it is still electric based, it provides an excellent source of heating in mild climates and is incredibly energy efficient.

We always recommend some alternate options in heating, so there is some source of heat in the event of grid failures. For example, if you have a geo-thermal heating system, install a wood stove as the back-up.
There are a number of structural changes or modifications which could result in much greater energy efficiency. These would include adding a vestibule or windbreak if you have children or go in and out of the house a good bit. You might be able to earth berm part of the north side of your house, or add a solar room to the south side of the home, just to name a few possibilities.

Bipartisan Energy Efficiency Bill On Verge Of Senate Breakthrough

While many in Washington still warn about the dangers of carbon emissions and climate change, the reality and perhaps the one thing that experts on both sides agree on, is that Americans are paying less attention to global warming than they have in the past. To end this uncertainty, the Senate after months of behind the scenes maneuvering will begin the debate on the critically important legislation which could help American consumers, businesses and the federal government to save millions of dollars each year by using less energy, and using less energy will be a step forward in the fight against climate change in the U.S.
The new energy efficiency legislation introduced by Senators Shaheen and Portman could come up before the U.S. Senate for approval. The Energy Savings and Industrial Competitiveness Act, also known as Shaheen-Portman Bill will help to reduce the energy bill of U.S., improve its economic competitiveness, create new American jobs and enhance U.S. energy security. The bill has been endorsed by more than 200 businesses, trade associations and advocacy groups.
What is the Energy Savings and Industrial Competitiveness Act?
The Shaheen-Portman Energy Efficiency Bill passed the Senate Energy and Natural Resources Committee by a 19-3 vote, it includes provisions that will directly improve energy efficiency in buildings, industrial processes and federal agencies, the provisions in the bill include strengthening energy efficiency requirements in building energy codes, incentivizing energy efficiency using rebates and for certain equipment, encouraging energy efficiency supply chains through a new supply star program.
The American Council for an Energy Efficient Economy (ACEEE) found implementation of the bill would save about 9.5 quadrillion btus (british thermal units) between 2014 and 2030, or nearly one tenth of the annual energy use in the U.S. As the second largest consumer of energy in the world and the worlds biggest economy it is critically important for the United States to improve energy efficiency, the bill has received bipartisan support with seven Republicans and twelve Democrats in favor of the bill. It contains a variety of policies and programs to reduce residential, commercial and industrial energy use and focusing on sectors and areas with energy savings potential such as the residential, commercial and industrial sectors, the bill also restricts inefficient energy practices that will cost the U.S. economy billions of dollars and millions of jobs every year. One of the components of the bill also requires the Federal Government- which is the largest user of energy adopt energy saving techniques and best practices to operate efficiently.
Commenting on the bill Senator Portman said Washington can seem pretty divided these days, but there are some things on which we all can agree. This bill is one of them it is good for the economy and good for the environment. By making it easier for employers to use energy efficient tools, we are helping them to reduce their costs, enabling them to put those savings towards expanding their companies and hiring new workers.
The bill has received positive feedback and widespread support, the only constraint halting the success of the bill are the amendments lawmakers are trying to attach to it. The successful passing of this bill will not only help in mitigating climate change in the U.S. and reduce carbon emissions but also be a trendsetter for other countries to follow suit.

Energy Efficiency And The Us Heavy Industry

Heavy Industry’ is a rather amorphous term. According to Wikipedia, Heavy Industry signifies the production of goods that are either heavy in weight or in the processes leading to their production.Examples of such industries include steel, chemical, mining, and construction equipment, machinery.

The United States is the largest consumer of energy in the world, using 94.9 quadrillion BTUs in 2009 and heavy industry in the United States accounts for about 31% of all energy consumption, significantly more than any other sector of the economy. Seven energy-intensive industries use three-fourths of this power; these are aluminum, chemicals, forest products, glass, metal casting, mining, and steel. All these heavy industries are also under tremendous pressure to reduce their huge dependence on expensive non
renewable energy.

A recent study by the European Commission thinks not. The study estimates that the United States has the potential to save about 45 TWh energy per year, through use of energy efficient transformers. Even a 0.01 percent gain in the average efficiency of utility transformers installed in the U.S. in a single year, can save as much as 2.9 Twh energy.

The environmental benefits of energy-efficient transformers are also significant and the study by the European Commission believes transformers could well emerge as a major focus for energy efficient
initiatives in the industry.

Is the Answer Energy-Efficiency

Energy efficiency is already playing a significant role in the Heavy Industry, but with growing concerns of greenhouse gas emissions and skyrocketing cost of energy, it obviously needs to do more.Before the 1970s, the U.S. energy consumption grew in parallel to gross domestic product (GDP). Had that trend continued, current U.S. energy demand would have more than doubled, currently, the energy consumption is 1.5 times that of 1970. Reduction in energy consumption has resulted from a combination of energy efficient methods and a shift from energy-intensive manufacturing toward a service and information-based economy.

Do Energy Efficient Transformers Hold the Key?

As energy costs rise and availability becomes uncertain, the necessity of utilizing energy-efficient products becomes imperative. Additionally, a globally competitive business environment is causing businesses to cut costs in order to remain competitive. Of particular interest are distribution transformers
that are the largest loss-making components in electrical networks.

In a typical grid, electric transformer loss contributes to about 40-50% of the total transmission and distribution loss. The Environmental Protection Agency (EPA) estimates that on a conservative estimate 61 billion kWh annually can be attributed to transformer losses. These losses cost end-users $3 to $4 billion annually. An energy-efficient transformer is therefore an important means to reduce transmission and distribution loss. Energy saving transformers can additionally save the equivalent of more than 70 million tons of CO2 emissions.

The answer to energy efficiency is in making distribution transformers efficient; and thankfully, manufacturers have the technical know-how to offer better, cost effective, low loss, energy efficient transformers.

Energy Efficient Distribution Transformers

Distribution transformers distribute power from power generating facilities to end-users and while energy loss during transmission is inevitable, measures are taken to reduce it considerably.However, for energy to be consumed voltage needs to be reduced and it is at this point of stepping down electricity that distribution transformers lose energy. Even though only a small portion of energy is lost it is in a permanent manner and standby power losses account for 2% of total electricity production.

Despite high average efficiencies of 95 to 99.75%, transformers have a significant environmental impact because they continuously consume power.

The energy losses in electricity transformers fall into two components, namely, no-load losses resulting from the energized iron core, which is a permanent phenomenon, and load losses, arising when providing power to users. Load losses also result from the resistance of the coil when the transformer is in use, and from eddy currents due to stray flux.

Technical solutions exist to reduce transformer losses by 75% at minimum when replaced by modern transformers or even by 90% when replacing transformers over 30 years old. Energy-efficiency can be improved with better transformer design, like selecting better, lower-core-loss steels; reducing flux density in a specific core by increasing the core size; increasing conductor cross-section to reduce current density; good balancing between the relative quantities of iron and copper in the core and coils.

An energy efficient transformer is an important means to reduce Transmission & Distribution loss and can save up to 120 TWh / year. Energy efficient transformers can provide considerable environmental benefits too. For example, a typical urban distribution transformer rated at 400 kW has lifetime losses equivalent to 125 “”184 tons of CO2 emissions; a more energy-efficient design can reduce these emissions to 56 tons.
