Geothermal Power: Could It Be A Good Quality Alternative Energy Solution?

By

Technology to take full advantage of the power of geothermal energy is actually an area that really needs to be explored. Geothermal energy is an area that has great opportunity but has really been underutilized. Our earth produces a tremendous amount of energy that has never been taken advantage of. As individuals walk around every day, they probably are totally unaware of the massive amount of power that lies beneath their feet. All we have to do is discover a way to take advantage of that energy for ourselves. The scorching heat at the center of the planet is 60 times hotter than that of hot boiling water. There is certainly a lot of energy merely a few miles below the Earth’s surface that have been created from the high temperature generated from the Earth’s core.

With obtaining simple and easy accessibility to info on several ways to going green matters, there may be just no pretext for not exploring tips on how to make a difference in the world right now. If you have at any time watched what takes place when a volcano erupts, you will understand that there is much power as well as energy in the magma, or superheated fluids. Much of the fluids arrive through as heavy steam through the natural air vents. To be able to create their own vents, and containment chambers for the magma, people may have energy converted into electrical energy to power their homes. To create a large scale geothermal plant, they would need to dig a well at an area that has large quantities of magma. The set up would most likely allow the steam to be moved through pipes to deliver energy. Enough of the steam would produce electrical power, by turning a turbine generator.

There are many issues that some men and women have about using geothermal energy on a large scale. There are some people today who think that it is too high priced to do more research and too time-consuming to find the right spot. In addition, the cost to produce a plant is high with no guarantee that it could make money. Once the areas are set up, they might not produce enough steam to be worthwhile. Additionally, some environmentalists are concerned that a geo-thermal plant may force up increased pollutants into the air.

But the advantages to using geothermal energy significantly outweighs the criticisms. More analysis will probably show that any health concerns with geothermal has to be minimal since it is coming up naturally from the Earth. Once a geothermal plant is made, managing the energy is not really that difficult making it a very efficient energy resource. The natural environment would be disrupted less, mainly because the plants are smaller than giant dams, atomic energy, or electrical facilities. As an alternative form of energy, the dependence on coal or petroleum would diminish.

One thing about geothermal energy is that it will for no reason run out, and it will not continuously be rising in price. Once the preliminary cost to build the infrastructure is paid back, geothermal will be a cheap energy resource. In the end this is a resource that we will come to depend upon.

When was the last time you truly prevailed at ways to going green now? It is true that men and women can fail so many times they basically get used to it. You are able to ease into something unique as ways to going green will describe very easily.

How Consumers and Builders Feel About Green Homes

By Leave a Comment

Benefit of Green HomesHere is the reality about green homes: they reduce carbon footprints, save consumers money on utility bills, and improve the health of children living in the home as a result of better air quality and other related factors. In a society with a growing focus on environmental sustainability, green homes are not just a potential future; they’re forming a part of our present.

But the reality about green homes and what the public actually thinks about them are not always one and the same. In fact, they can be disparate enough that it would warrant continued action by organizations supporting green homes to increase awareness about the benefits of these homes and to dispel any myths.

Whirlpool Corporation is interested in seeing that green building takes hold in our society. Whirlpool has been a partner of Habitat for Humanity for years, donating ranges and ENERGY STAR® qualified refrigerators to new Habitat homes built in the United States and Canada as well as supporting Habitat’s work around the world, and engaging employees to volunteer with their local Habitat organizations. To gauge public perception on the topic of green homes, Whirlpool and Habitat teamed up with NAHB Research Center – an independent subsidiary of the National Association of Home Builders (NAHB) – to survey consumers and builders on what they think is the state of affordable and green housing in the United States. Whirlpool is releasing the results from this survey in a series, with the first set of results on the affordability of green homes released in November 2010 and the second, identifying barriers to green homes released in January 2011.

The survey found that builders and consumers generally perceive green homes as affordable to live in but more expensive to purchase. In fact, among consumers, 67 percent of high-income respondents said they believe a completely green home would be affordable to live in or maintain. The same answer was given by 65 percent of upper middle income, 59 percent of middle income and 48 percent of low income consumer respondents.

But, when asked if a green home would be affordable to purchase, only high income respondents answered mostly in the affirmative, with a total of 71 percent, compared to 47 percent of low-income respondents who said that they believe a completely green home would not be affordable for them to purchase.

The builder portion of the survey found that 87 percent believe green homes are affordable for middle-income families to live in, but 30 percent felt green homes were not affordable for the segment to purchase or build. The disparity is even more evident when asked about low-income families. A total of 70 percent of home builders said they believe green homes are affordable to live in for this segment, but almost 60 percent thought green homes were not affordable for low-income families to purchase or build.

However, the survey also demonstrated that the public is generally in favor of a continued effort for creating more green homes. It showed that 64 percent of respondents indicated that savings from green home features were sometimes worth the added costs and efforts. And, 77 percent of consumers feel that green homes are at least somewhat, if not very, important to them. And they note that green homes are important because of the positive impact on the environment, the long-term financial savings, and the health benefits for the family. It seems clear that the public believes in the importance of green homes, so what do consumers and builders believe will help them become more affordable? According to the survey, the answer lies in reduced prices on materials for construction. A total of 59 percent of consumers indicated that lower cost of products and materials is needed for green homes to become more affordable and 75 percent of builders agreed with this.

Another change consumers mentioned that can make green homes affordable is an increase in incentives for sustainable building and remodeling. Of all respondents, 53 percent felt that increasing incentives for homeowners would help with green home affordability, and 36 percent suggested increasing incentives for builders. In addition, 69 percent of consumers indicated they believe state and federal governments should provide incentives for purchasing green building products. Among builder respondents, 40 percent believed that incentives for both homeowners and builders would help promote green building.

This survey underscores a case for the viability of green building to protect the environment and save money. More findings from the study will be released throughout the year. While these will undoubtedly offer additional insight into how we can all help promote green building, the findings we have thus far clearly show us that this is something the public is looking for. It’s up to the companies and organizations involved in green building to help educate the public further on why this is such an important endeavor and why it can be affordable to all.

Editor’s note: In a earlier post in this series, Shon Anderson, VP of Energy Solutions at Schneider Electric points out that 70-75% of the total life-cycle cost of a building is in operation and maintenance and only 20-25% is tied up in the purchase price. Why then do we allow the high initial cost to be such a barrier? These costs should be amortized of the home’s life cycle. This would be a great opportunity, not only for government subsidies, but for the financial industry to step forward and provide mechanisms to make this happen.

Common Home Problems and Solutions

By Leave a Comment

energy-efficient-homeIs your home cold, drafty, or uncomfortable? Do you have high energy bills? Ice dams? Peeling paint? Excessive dust? Addressing these types of home problems can make your home more comfortable, and at the same time improve its energy efficiency — saving you money on utility bills and helping to protect the environment too.

High Energy Bills

High utility bills in summer and winter can often be traced to air leaks in your home’s envelope, inefficient windows or inefficient or incorrectly installed heating and cooling equipment, or poorly sealed and insulated ducts.

Mold, Mildew or Musty Odors

Water leaks or high humidity can lead to mold and mildew. This can cause wood rot, structural damage, peeling paint, and a variety of health problems. Often, high humidity in homes with central air conditioners can be traced to improperly sized or installed air conditioners.

Damp Basement

A damp basement is commonly caused by moisture migrating through the foundation. As this moisture evaporates, it increases indoor humidity and can promote the growth of mold — resulting in an uncomfortable house.

Cold Floors in Winter

Some types of floor coverings (such as wood, stone, tile, or concrete) will naturally feel cold on bare feet. However, insufficient insulation or air infiltration can also cause cold floors.

Drafty Rooms

Cold air coming into or going out of your house, especially through leaks hidden in the attic and basement, can cause rooms to feel drafty and uncomfortable.

Dust

Increased dust could be a sign that it is time to change your air filter or that your ductwork is not well sealed.

Moisture on Windows

Inefficient windows or high indoor moisture levels from air leaks can result in condensation, frost, or pools of water on windows and sills.

Ice Dams

Warm air inside your home leaks into the attic and will warm the underside of the roof causing snow and ice to melt and refreeze as it runs off your roof — forming icicles and ice dams.

Peeling Paint

Peeling or cracking paint on your home’s exterior may be a sign of a humidity problem or improper paint application.

Hot or Cold Rooms

Significant differences in temperature from one room to another could be caused by several factors, including inadequate insulation, air leakage, poor duct performance, and improperly installed heating, ventilation, and air conditioning (HVAC) system.

Dry Indoor Air in Winter

Air leaks in your home allow warm humid air to escape and draw in drier colder air.

What is the Definition of a Green Home?

By Leave a Comment

green-homeThe term green home is being used more and more often in the residential building industry, but what does it really mean. According to the Green Building Council of Australia a green house is “a high performing home that is energy and water efficient, has good indoor air quality, uses environmentally sustainable materials and also uses the building site in a sustainable manner”. A green home also requires a holistic approach, beginning at the design stage and continuing on through the construction process and the eventual day-to-day running of the home. The main goal of these characteristics is to reduce the environmental impact a home will have over the course of its lifetime.

As mentioned above, a green house should begin at the design stage. Incorporating green design elements at the initial stages of a home construction will ensure the home can take advantage of the surrounding natural environment. By utilising the topography of the site, sunlight and breezes a green home can significantly reduce its dependence on additional heating and cooling sources. This saves the occupants money on their energy bills and reduces the production of greenhouse gases.

Choosing recycled and environmentally friendly building products is another important element of a green home. The type of materials used can affect the homes’ environmental impact and the health of the homes’ eventual residents. A green home utilises recycled timber or sustainable harvested plantation lumber for its structural and cosmetic components. It is also possible to use a range of other natural products in the construction of a green home, such as straw, mud, hemp and dirt. Although some of these materials are not conventional building products, it does not mean a green home has to look very different from a regular home. Many of the materials and finishes in a regular home contain formaldehyde and volatile organic chemicals (VOCs). Once installed in a home they continue to release gases which can be harmful to the people living in them. A green home uses materials and finishes with low or no VOCs that ensure good indoor air quality.

A green home also minimises the use of energy and water by using efficient materials and products. Water saving devices in the bathroom, toilet and laundry significantly reduces water consumption. Collection of rainwater and the recycling of grey water can further improve water efficiencies. Insulation in walls and ceilings helps maintain a constant indoor temperature reducing the need for mechanical heating and cooling. Energy and water efficient appliances can also be found in this home. They reduce environmental impacts and keep running costs down for the occupants.

Consideration of these factors and the inclusion of sustainable building techniques and materials make a green home use energy and water efficiently, provide a healthy environment for the occupants and reduce the environmental impacts over the lifetime of the dwelling.

Damp Basement Solutions

Damp Basement

Diagnosis:

The source of your problem could be a water leak or high humidity. Both can lead to mold, mildew, or other biological growth. Depending on the severity, conditions can lead to rot, structural damage, premature paint failure, and a variety of health problems. Water can seep into your house from the outside through a leak in the foundation, or small gaps around windows or doors. Water can also come from inside your house from a leaking water pipe, toilet, shower or bathtub. High indoor humidity caused by normal activities of everyday living, such as showering, cooking, and drying clothes, can also be a source of your problem. A damp basement is commonly caused by moisture migrating through a concrete foundation. There may not be a sign of any leak or standing water, but the moisture evaporates, increasing indoor humidity. Another common cause is condensation on the cold concrete walls and floors during humid months.

Prescription Checklist:

* Where does the problem occur? Below a bathroom? Ceiling? Corners? Where the problem occurs can lead to what is causing the problem. If the problem is localized (a spot on the ceiling, wall or corner it is possibly caused by a water leak. If the problem is in a large area, like a whole wall or room, then it might be caused by humidity.
* If you suspect a mold problem consult EPA’s Brief Guide to Mold in your home for more information.
* If you plan to remodel your basement, it is important to control moisture problems at the before doing anything else. Corrective actions can be relatively easily but sometimes, depending on the severity of the problem, they can be difficult and expensive.

Stop water leaks

* If a leak is the source of your problem, have it fixed first.
* If you have standing water on the floor of your basement after a heavy rain then it is likely from a leak in the foundation.
o Clean rain gutter and redirect downspout runoff away from the foundation.
o Make sure the ground around the house slopes down away from the foundation. If necessary, re-grade so the ground does slopes away.
o If you have a sump pump, make sure it is working properly.
* If you have water stains on the ceiling or wall under or near a bathroom it could be a leak from a water pipe, toilet, bathtub or shower. Hire a plumber to repair the leak.
* If the leak has caused substantial water damage or mold you will want to hire a contractor who specializes in mold remediation and water damage repairs.

Reducing indoor humidity

* If your basement has a dirt floor, cover the floor completely with plastic to slow down water vapor coming through the soil.
* Use ventilation fans in kitchens and baths to control moisture. Check to make sure ventilation fans venting directly outside. In some cases the vent fan may have been installed to vent into the attic or become disconnected or blocked.
* Your clothes dryer should be vented directly to the outside. Inspect the vent duct. Make sure it is attached securely to the dryer. Check that it is clear of obstructions (e.g. lint). Check for holes that leak air. If vent duct is damaged replace it with a metal duct. The vent duct should be cleaned at least once a year. The Consumer Products Safety Commission additional safety tips for dryer vents Exit ENERGY STAR.
* Ask a heating and cooling contractor to check your heating and cooling system to make sure it is sized and operating properly to remove humidity. If you system is too big or the airflow incorrect your air conditioner will not remove humidity like it should. Also, ask the contractor to check your duct system for air leaks, and proper size and air flow to each room. To help you find a contractor, please refer to our recommendations.
* Sealing air leaks (Home Sealing) and sealing duct air leaks can help to prevent high humidity levels in your home.
* During hot humid months, using a dehumidifier in the basement can reduce condensation on the walls. This may work better after you’ve sealed air and duct leaks to reduce the amount of humid outdoor air you are bringing into the basement.
