Most people don’t know how easy it is to make their homes run on less energy, and here at InterNACHI, we want to change that. Drastic reductions in heating, cooling and electricity costs can be accomplished through very simple changes, most of which homeowners can do themselves. Of course, for homeowners who want to take advantage of the most up-to-date knowledge and systems in home energy efficiency, InterNACHI energy auditors can perform in-depth testing to find the best energy solutions for your particular home.
Why make your home more energy efficient? Here are a few good reasons:
1. Find better ways to heat and cool your house.
- Install a ceiling fan. Ceiling fans can be used in place of air conditioners, which require a large amount of energy.
- Periodically replace air filters in air conditioners and heaters.
2. Install a tankless water heater.
3. Replace incandescent lights.
Use CFL's or LED's
4. Seal and insulate your home.
Go to HomeDepot and get a can of spary faom and fill in those cracks.
5. Install efficient showerheads and toilets.
6. Use appliances and electronics responsibly.
7. Install daylighting as an alternative to electrical lighting.
8. Insulate windows and doors.
9. Cook smart.
- Microwave ovens consume approximately 80% less energy than ovens.
- Pans should be placed on the matching size heating element or flame.
- Using lids on pots and pans will heat food more quickly than cooking in uncovered pots and pans.
- Pressure cookers reduce cooking time dramatically.
10. Change the way you do laundry.

Solar energy is a terrific selection
The following are benefits of solar power:
Basic material are sustainable and unlimited. The quantity of readily available solar energy is staggering-- roughly 10,000 times that currently needed by people-- and it's constantly replaced. A mere 0.02 % of inbound sunlight, if caught properly, would be sufficient to change every other fuel source currently used.
Given, the Earth does require much of this solar energy to take its weather, so let's look only at the unused portion of sunshine that is mirrored back into area, referred to as the albedo. Earth's typical albedo is around 30 %, suggesting that about 52 petawatts of energy is mirrored by the Earth and lost into area every year. Compare this number with international energy-consumption data. Each year, the energy lost to space is the consolidated equivalent of 400 hurricanes, 1 million Hoover Dams, Great Britain's energy demand for 250,000 years, around the world oil, gas and coal production for 387 years, 75 million automobiles, and 50 million 747s running constantly for one year (not to mention 1 million fictional DeLorean time machines!).
Solar power is low-emission. Photovoltaic panel produce no pollution, although they impose environmental costs through manufacture and construction. These ecological tolls are negligible, nevertheless, when compared to the damage inflicted by standard energy sources: the burning of nonrenewable fuel sources releases about 21.3 billion metric tons of carbon dioxide into the atmosphere each year.
Solar power is suitable for remote areas that are not linked to energy grids. It might come as a surprise to city-dwellers but, according to Home Power Magazine, since 2006, 180,000 houses in the United States were off-grid, which figure is likely substantially greater today. California, Colorado, Maine, Oregon, Vermont and Washington have long been havens for such energy rebels, though people live off the grid in every state. While many of these people shun the grid on principle, owing to politics and environmental concerns, few of the world's 1.8 billion off-the-gridders have any choice in the matter. Solar power can drastically enhance the quality of life for millions of people who live in the dark, especially in places such as Sub-Saharan Africa, where as many as 90 % of the rural population lacks access to electricity. People in these areas have to depend on fuel-based lighting, which inflicts considerable social and environmental expenses, from jeopardized health through Rural, off-grid houses are exceptional applications for solar powercontamination of indoor air, to limited overall efficiency.
Solar energy supplies green jobs. Manufacturing of photovoltaic panels for domestic use is ending up being a growing source of work in research, manufacture, sales and setup.
Photovoltaic panel contain no moving parts and thus produce no sound. Wind turbines, by contrast, require noisy gearboxes and blades.
In the long run, solar energy is economical. Solar panels and installation include high initial expenditures, but this cost is soon balanced out by cost savings on energy expenses. Eventually, they might even produce a revenue on their use.
Solar energy makes the most of net metering, which is the practice of crediting homeowners for electrical energy they produce and go back to the power grid. As part of the Energy Policy Act of 2005, public electrical energies are needed to offer, upon demand, net metering to their Manhattan, and much of the northeast UNITED STATE, goes dark in August, 2003customers. This practice provides a benefit for house owners who utilize solar panels (or wind turbines or fuel cells) that could, sometimes, produce more energy than their houses require. If net metering is not a choice, excess energy could be stored in batteries.
Solar power can suggest government tax credits. U.S. federal subsidies credit approximately 30 % of system costs, and each state offers its own rewards. California, blessed with abundant sunshine and afflicted by high electric rates and an over-taxed grid, was the first state to provide generous renewable-energy incentives for houses and companies.
Solar energy is dependable. Numerous property owners prefer solar power since it is virtually immune to prospective failings of energy companies, primarily in the form of political or economic chaos, terrorism, natural catastrophes, or brownouts due to overuse. The Northeast Blackout of 2003 unplugged 55 million individuals across two nations, while rolling blackouts belong of routine life in some South Eastern nations, and occasionally in California and Texas.
Solar energy conserves foreign energy expenditures. In many nations, a huge portion of earnings is utilized to pay for imported oil for power generation. The United States alone spends $13 million per hour on oil, much of which comes from Persian Gulf countries. As oil supplies diminish and costs increase in this politically unpredictable region, these problems continue to militarize the growth of solar energy and other alternative-energy systems.
In summary, solar power offers advantages to conventional fossil fuels and other renewable energy systems.
