Good passive solar design will provide enough sunlight into the rooms to be absorbed by the surrounding thermal mass (usually masonry materials). So that the heat will be given back into the room when the sun goes down. In fact the thermal mass is a kind of "heat battery" that stores the warmth, absorbing the warmth to keep the room from getting too hot during the day.

The graph demonstrate the process of heat with the sun for you:

And equally important to thermal mass is insulation, such as straw bales or crushed volcanic rock. Insulation will keep that heat inside.

It's a cool way to make your home green by utilizing green energy, such as solar power, wind energy. It not only reduces our carbon footprint, but also reduce our energy bill.

Wind Energy for green home:

And in some areas, especially the remote areas with a few populations, it's ideal for us to install wind turbines for a green life. But wind energy for our green home is a new option. We will meet several problems when applying wind energy for our cool green building.

Two common questions are: do wind turbines make noise? Do wind turbines interfere with TV reception?

Home wind turbines are a relatively new option for families who are trying to invest in more green, renewable, alternative energy sources. Although it is common for people in sunny areas to look into getting solar panels, home wind turbines are a relatively new technology. There are now several different residential wind turbine options on the market. Depending on how much energy you want to get from wind power (wind energy), home wind turbines can range anywhere from about $500 to $22,000 for installation.

Home wind turbines can be used to reduce your carbon footprint, lower energy bills or even move entirely off the grid depending on what your goals are.

The most common use for the home wind turbine is just to reduce the amount of energy you use from more traditional (such as coal, nuclear, oil) power plants. Everybody can do this, however it will depend on where you live. For some areas it may be not cost effective with home wind turbines. Below we explain it to you.

There are two main forms of solar systems for residential use: the "grid-tie" home solar power system, and the "off-grid" or stand-alone home solar power system.

In a grid-tie home solar energy system, a home has solar cells. And the home is still connected to the local power grid. The home solar power system includes solar cells installed on or near a home that collect the sun's energy and convert it into DC electricity. Then the inverter converts the DC power into AC power, which can then be used directly in your green home.

If installing your own home solar system is out of your reach, you may want to consider switching to an accredited green energy provider for residential solar energy (solar power) or another Green Energy source. In fact green energy can come from solar, wind, or hydroelectricity, or other green sources. The companies that offer these programs are bound to ensure that the green energy they sell you under this banner is actually from the renewable sources stated.

Four major considerations about solar power for your green home.

1. How much solar electricity do I need to supply my home?

You can find advertisements anywhere for different arrays stating "1500 watts" and the like, however what does that mean? Find out what different solar array outputs will do for you in regards to powering your green home.

2. What is the current status of Government rebates for home solar power installation in my area?

Below we list some actions for going green with our home.

1. A direct way of using renewable energy (green energy) is to install renewable energy (green energy) generating equipment like solar panels or wind turbines for our home.

These renewable energy (green energy) generating equipmens can be cost-effective, particularly in rural areas where the only alternative is extending long electric distribution lines to serve the house or another small load. You use solar panels to pump water in a cost-effective manner. You can also choose to augment their existing utility power with solar panels. In such arrangement, you reduce the electric bill by generating a portion of your own power needs.

Solar water heaters are another great technology we can apply in our home. Although these solar water heaters don't generate electricity, they do reduce the need for electricity or gas for your water heater. in fact, solar water heaters can provide 50-80% of the hot water needs for typical homes and businesses.

The technology of green energy is developing quickly. With all the advances, it is easier than ever to start converting your home into a green energy (alternative energy) home. A green energy home utilizes renewable or green resources to provide electricity, hot water, heat and peace of mind.

There are several ways to implement your green energy home plan.

The first is solar energy (solar power).

In a green energy home you can install solar hot water panels which heat and store water for use. And you can install solar panels. These solar panels use photovoltaic cells to convert sunlight into electricity.

Renewable power sources are naturally replenished and are not depleted by use, unlike conventional fossil fuel resources.

Geothermal, wave, tidal, ocean current, hydro, wind, solar, and biomass are the most common renewable resources used in our life to generate renewable energy (sustainable energy).

Increasing levels of energy-related environmental degradation in both industrialized and developing countries have led to recognizing the need for improved energy options for sustainable development. In fact environmental and social concerns must be incorporated early at the regional and sectoral planning stages in order to ensure sustainable development. The important role is the concern about green energy (also called sustainable energy).

The estimated U.S. energy use in 2008 equaled 99.2 quadrillion BTUs (“quads”), down from 101.5 quadrillion BTUs in 2007. (A BTU or British Thermal Unit is a unit of measurement for energy, and is equivalent to about 1.055 kilojoules).

Energy use in the industrial and transportation sectors declined by 1.17 and 0.9 quads respectively, while commercial and residential use slightly climbed. The drop in transportation and industrial use - which are both heavily dependent on petroleum - can be attributed to a spike in oil prices in summer 2008.

As the global demand for clean, reliable, renewable energy increases, geothermal energy has become an attractive solution. This is true not only in the United States, but at numerous locations around the world. One area of increased emphasis is Enhanced Geothermal Systems (EGS) which offers the possibility of widely expanding the geographic range of geothermal power plant locations.

Electricity generated from geothermal energy (geothermal power) offers a number of advantages:
1. Reliability
2. Renewability
3. Combustion-free
4. Very low emissions
5. Reduction in global warming
6. Domestic economic boon
7. Minimal land impact
8. Water conservation
9. Flexible plant growth

However, there are some disadvantages to the production of electricity from geothermal power sources:
1. Limited geographic site locations
2. High start-up cost
3. Land subsidence may occur
4. Poor management can exhaust sites
