ICF Insulating Concrete Form or

Insulated Concrete Form (ICF) is a system of formwork for reinforced concrete that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs. The forms are interlocking modular units that are dry-stacked (without mortar) and filled with concrete.

The forms lock together somewhat like Lego bricks and serve to create a form for the structural walls or floors of a building. ICF construction has become commonplace for both low rise commercial and high performance residential construction as more stringent energy efficiency and natural disaster resistant building codes are adopted

Have your own power plant (Solar or Wind) instead of conventional

Why Need to Have Own Power Plant

Do you know why you need to have your own power plant?This is very essential because you can reduce your electricity cost 80-100% having your own power plant and can also get extra cash from power company for your contribution to the grid, build you own windmill or solar plant in a cheap rate, contribute to make our pollution free greener world and get a modern technology to generate your own electricity. Would you now depend on land line telephone or hand written letter to communicate other? Because now you got most updated technology such as mobile, laptop, email and internet to do these works swiftly. So why do you stay with conventional way to get your regular electricity? Let us be updated with your own power plant with Solar Plant or Windmill. Now we do our maximum work by electricity but some time the electricity bill shock us having a great amount. Now this is the time to make shocked your electricity provider and enjoy some extra contributing to Power Company.

Electricity Generation, Conventional Way to Modern

In conventional way, power company generates electricity based on fuel (coal and natural gas) that are decreasing rapidly now due to increase of using electricity much. To become more updated we are using much electricity, but when the natural fuel goes down, what will happen? Will we go back to ancient darkest life? To avoid this circumstance, we need to be aware right now. We need to find more energy sources especially renewable energy that has an unlimited source. There are many sources of renewable energy like: Wind power, Hydropower, Solar energy, Biomass, Bio-fuel, Geothermal energy etc. But for your household small scale application of electricity, Solar Plant and Windmill is much easier to set up, simple to use and very cost effective. Also Nuclear Power Plant can produce much electricity, but have a great impact on environment. In conventional way, you get electricity by connecting your home appliance to grid line. But when grid fails to provide electricity, you face sudden problem to run your regular activity. But when you have your own power plant, you will be well informed about your power plant activities. When it supplies maximum, when got problem, when it produce extra and so on. As its source is unlimited, you do not need any fuel to run it. Also you do not need to complain other, can manage it yourself. Now you can buy power plant, not only power. Buy for one time and get the benefit for long time.

Contribute to Green Energy

Our conventional fuel based power plant makes much pollution over the world. For these many reasons, now we are afraid for global warming, increased sea level, climate change and different types of pollutions. Also collecting the natural gas and coal continuously is very harmful for our natural resource. Fuel based power plant makes much CO2 and other harmful gases. But our environment friendly renewable energy does not make this harmful gas. It uses only natural unlimited sources like Sun Energy, Wind, Earth Energy, Roof Energy, Wall Energy, Rain Energy etc. those are sustainable and unlimited. Now many countries depend on nuclear power plant to produce more electricity which is very harmful for environment. If we have our own small power plants, then Power Company does not feel more stress to produce more electricity and our environment also become sustainable for all. We can not replace all the fuel based power plant at now with renewable energy. But if we take steps to have our own power plant right now, then it will have a great impact in future. Also collection of coal and natural gas will reduce that will have a good impact on earth.

How to Get Own Power Plant

To set own power plant, you do not need to have much larger area. You can use your veranda or roof top or open yard where sun is available for solar power plant and free access to wind for windmill. Calculate your home power consumption and then think how much kilowatt system you need. If your home is near to river or ocean or have much open area to have air, then you can select windmill as your own power plant. If you live at much sunny area, then you can choose solar power plant and install them on roof top or veranda facing outside the panel or yard. Whatever you choose, you will get continuous power from your own power plant for your home appliance. When your home electricity demand will fulfill by your power plant, the power grid will feed from your power plant. Your net meter will show how much electricity you consumed for your home and how much electricity fed by power grid. Then you will get the bill from power Grid Company for supplying the electricity to them. This will be an earning source for you. Also you may store some power for cloudy and rainy day using battery or for your extra use in future.

Some Viable Natural Energy Sources for your Electricity Demand

Solar EnergySolar Panels consist of a number of solar cells that directly convert solar energy to D. C. Power. These cells are made of semiconductors that generate electricity when they absorb light. Solar cells represent the fundamental power conversion unit of a photovoltaic system.

Using solar panels is a very practical way to produce electricity for many applications. The obvious would have to be off-grid living. Living off-grid means living in a location that is not serviced by the main electric utility grid. Remote homes and cabins benefit nicely from solar power systems. No longer is it necessary to pay huge fees for the installation of electric utility poles and cabling from the nearest main grid access point. A solar electric system is potentially less expensive and can provide power for upwards of three decades if properly maintained.

Expected Benefits

Solar system provides clean power for sustainable solution for a very long time. This ensures a definite positive payback.The Perfect solution for a stand-alone system:The system runs by solar power, which is available in all places, and thus, it can be operated everywhere the sun can go. So, the proposed, system offers you a perfect hassle-free power solution to run your desired loads at your proposed site.

Zero Running CostThe system uses the abundant and free solar energy as fuel, which makes the power generation absolutely running cost free.

Least Maintenance and Hassle Free Power Solution

The regular maintenance of the system includes only cleaning the dust of the module once a week. Also there is no tension of buying, carrying or safe storing of flammable, versatile fuel like petrol or diesel etc. And the power system handling is also a matter of only on-off switch which makes it hassle free.

Silent-Safe-Simple Power Solution

The solar system will get rid of the generator noise and fume. And also it is a mean to provide power, which is safe, both to the environment and the user. The solar system technologies like maintenance, troubleshooting, replacement etc. are also not too much critical or technical even for a general person.

Environmental BenefitsOne of the main advantages of Solar Photovoltaic Technology is its environmental compatibility, especially as this alternative is immune from emission of pollutants including the Green House Gases.

Different Kinds of Solar ModuleMono-crystalline, Poly or Multi-crystalline and Amorphous or Thin Film are the most commonly used solar cells over the world. These three has different characteristics based on their crystalline. Mono-crystalline cell has high efficiency and long life span. This is most popular and widely used. Multi-crystalline cell can absorb solar radiation in different angles. But it has lower life span than mono-crystalline cells. Thin Film cell has low manufacturing cost, but it also has low efficiency and life span. Also it has some re-cycling problem, so this is not more environment friendly.

Wind Energy

Wind EnergyWind is known to be another form of solar energy because it comes about as a result of uneven heating of the atmosphere by the sun coupled with the abstract topography of the earth’s surface. With wind turbines, two categories of winds are relevant to their applications, namely local winds and planetary winds. The latter is the most dominant and it is usually a major factor in deciding sites for very effective wind turbines especially with the horizontal axis types.

Benefits of Wind TurbinePower is stored in batteries, so it is available for any application anytime, regardless of wind conditions. WIND TURBINE can also be combined with solar panels to further increase power production. WIND TURBINE's unique vertical design makes it a more versatile, reliable and efficient way to produce pollution- free, renewable electricity.

Benefits of Wind Turbine Completely silent! Produces up to 50% more electricity annually versus

comparable propeller-type turbines. Compact footprint is smaller, lighter and quieter than

the competition and requires little or no maintenance. The omni-directional design reacts immediately to

changes in wind direction and speed and generates electricity in winds as low as 6 kmh (4 kmh). Engineered to withstand extreme weather conditions

such as frost, ice, sand, humidity and can handle winds over 210 kph (130 mph).

Environmentally and wildlife friendly -- birds see these VAWTs as solid objects so they don't fly into them!

Geothermal Energy- Geothermal means earth-heatGeothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth's crust originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%).

Where Does Geothermal Energy Come From?

Geothermal energy has two primary sources, primordial heat, and radioactive decay. Primordial heat is what resulted from the creation of Earth 4.5 billion years ago, when the energy and mass from colliding cosmic matter made Earth a large, hot piece of space debris. As Earth’s outside cooled, it then acted as an insulator for the heat in the middle, which is why Earth is still cool and hospitable on the outside, and hot-rock and metal at its core.

How Can We Use Geothermal Energy?

A vast majority of the world’s power production involves the use of hot water. Sources like nuclear, coal and natural gas harness different processes (i.e. radioactive decay, combustion) to heat water into steam, which is run through a turbine to generate electricity. Geothermal energy uses the escaping heat from Earth’s core as a means to heat water and produce electricity. By drilling deep into the Earth’s interior, we find temperatures suitably high to produce electricity.

How Can We Use Geothermal Energy?

Sometimes when we drill deep, there is hot water where the rock is porous (has space for fluids). In this case, we can extract the water from depth and through specialized equipment, use it to produce electricity (explained further on). If there is no water, but the rocks are very hot where we drill, it is possible to inject water to create an enhanced geothermal system (EGS) and hot water where it did not exist before. By using Earth’s thermal energy to heat water instead of processes with harmful by-products like coal and nuclear, geothermal energy can produce clean, reliable electricity as long as heat continues to seep from Earth’s interior (as it has for 4.5 billion years). Further, it is sustainable power because once we have extracted the thermal energy from the water or steam, it can be continuously re-injected deep underground to obtain more geothermal heat.

How is Electricity Produced from Geothermal Heat?

There are two commonly used processes when creating electricity from geothermal sources. The first, flash geothermal, is generally associated with higher temperature geothermal sources ( >180°C). Because the pressure of the subsurface environment is much greater than at the Earth’s surface, water can exist as a liquid at very high temperatures. The high temperature, high pressure water is brought to surface, where it is enters a low pressure chamber and ‘flashes’ into steam. The pressure created by this steam is channeled through a turbine, which spins to generate electrical power. Once the steam has exited the turbine, it is either released into the atmosphere as water vapor, or it cools back into liquid water and is injected back underground.

How Can We Use Geothermal Energy?

Heat is sitting under the Earth-- we just need to tap it. Geothermal energy can be used in three ways:

1. Direct geothermal energy2. Geothermal heat pump3. Geothermal power plant

Direct Geothermal Energy In areas where hot springs or geothermal

reservoirs are near the Earth's surface, hot water can be piped in directly to heat homes or office buildings. Geothermal water is pumped through a heat exchanger, which transfers the heat from the water into the building's heating system. The used water is injected back down a well into the reservoir to be reheated and used again.

Geothermal heat pump A few feet under the ground, the soil or water

remain a constant 50 to 60 degrees Fahrenheit (10-15 degrees Celsius) year-round. Just that little bit of warmth can be used to heat or cool homes and offices. Fluid circulates through a series of pipes (called a loop) under the ground or beneath the water of a pond or lake and into a building. An electric compressor and heat exchanger pull the heat from the pipes and send it via a duct system throughout the building. In the summer the process is reversed. The pipes draw heat away from the house and carry it to the ground or water outside, where it is absorbed.

Geothermal power plantHot water and steam from deep underground can be piped up

through underground wells and used to generate electricity in a power plant. Three different types of geothermal power plants exist:

Dry steam plants. Hot steam is piped directly from geothermal reservoirs into generators in the power plant. The steam spins turbines, which generate electricity.

Flash steam plants. Water that's between 300 and 700 degrees Fahrenheit (148 and 371 degrees Celsius) is brought up through a well. Some of the water turns to steam, which drives the turbines. When the steam cools it condenses back into water and is returned to the ground.

Binary cycle plants. Moderately hot geothermal water is passed through a heat exchanger, where its heat is transferred to a liquid (such as isobutene) that boils at a lower temperature than water. When that fluid is heated it turns to steam, which spins the turbines.

Snow & Ice Melting System

---A Modern Use of Geothermal Energy

Snow & Ice Melting System A snowmelt system is used to remove snow

and ice via embedded electric cables or hydronic tubing. Common areas for snowmelt systems are: driveways, walkways, parking areas, stairways, wheelchair ramps, loading docks, and around car washes. A snowmelt system is usually installed during the original construction in concrete, asphalt, mastic asphalt or under pavers. Retrofit electric systems can also be installed using saw cutting technology or on top of existing concrete, asphalt, or mastic asphalt surfaces if the existing surface is on grade.

Snow & Ice Melting with Geothermal Energy

Snow & Ice melting with geothermal water has increased during the last two decades and now most new car parking areas in regions enjoying geothermal district heating are provided with snow melting systems. Geothermal water from space heating returns at about 35°C , and is commonly used for de-icing sidewalks and parking spaces. Geothermal energy has been utilized to a limited extent to heat pavements and melt snow during the winter.

Snow & Ice Melting with Geothermal Energy

Most systems have the possibility of mixing the return water with incoming hot water (80°C) when the load is high.

Road Construction for Snow & Ice Melting System with Geothermal Energy

Snow & Ice Melting System for Car Parking To ensure exceptional comfort while achieving highly efficient

HVAC operation in a building, which features a dramatic floor-to-ceiling glass window wall design, a REHAU radiant heating system was installed. This included two levels of new and pre-owned vehicle showrooms, as well as the dealership’s customer service, reception and lounge areas.

Radiant heating not only promotes energy efficient HVAC operation and ultimate occupant comfort, but, as a ventless system, will also minimize the dust on the vehicles and building windows.

Efficiency Most new snowmelt systems operate in

conjunction with an automatic activation device that will trigger the system on when it senses precipitation and freezing temperatures. These types of devices ensure the system is only active during useful periods and reduces wasteful energy consumption. A high limit thermostat further increases efficiency when installed in conjunction with the automatic snow melt controller to temporarily disable the system once the slab has reached a sufficient snow melting temperature.

Environmentally friendly

Snowmelt systems are environmentally friendly compared to the use of salt and chemicals to melt the snow, which causes calcium chloride to run into rivers and watersheds. Current systems are more cost effective in the long run than continual salt dumping and removal, and reduce waste by extending the life of the cement.

Roof EnergyThe Energy Roof is the application of an Energy Wall applied to the roof structure of the building

Roof Energy- The Energy Roof will offer the use of free, renewable, and clean energy, and can help defray the rising cost of conventional energy.  Energy Wall systems absorb thermal energy from directs sunlight to heat air; this heated air can then be circulated throughout the buildings to provide heat or by using a heat pump that same energy developed by the Energy Roof can be converted to Air Condition AC.

- One of the advantages of the Energy Roof is that you can apply solar panel on the roof without interfering with the Energy Roof system combining Energy Roof and Solar Energy Roof.

Wall EnergyEnergy Wall not only provide Source of energy, it also provides fresh Air, Fresh Heat

Solar Wall, solar air heating system is a great source of Wall Energy

Solar Wall The solar Wall air heating system is a custom

engineered solution containing many internal and external components. It uses solar energy to heat and ventilate indoor spaces in new and retrofit applications, as well as to heat air for manufacturing process and agricultural crop drying applications. The system design is optimized to maximize energy delivery with a minimum amount of static pressure in the airflow.

Solar Wall systems are building integrated, contain no moving parts, and are virtually maintenance free. Installing a system over a masonry wall also protects the wall form rain and moisture, which can cause bricks to crumble.

Thermal Energy Thermal energy is the part of the total

potential energy and kinetic energy of an object or sample of matter that results in the system temperature.

Solar thermal systems harness the heat of the sun to heat water directly. They can provide all of your hot water needs during the summer but will need to be combined with another source of hot water during the winter.

THERMAL ENERGYA solar thermal system consists of a collector panel which absorbs the energy from the sun and transfers it to a working fluid (usually water). This is pumped around a loop which transfers the heat collected to a hot water or buffer tank, either directly or through a heat exchanger. The pump is often powered by a small PV panel, which means that no external electricity is required. Finally, there is a control system which determines when to pump the fluid around, depending on the level of heat being provided by the sun at the time.

Rain Water Harvesting For Natural Clean Water Source Rain water harvesting units could prove to be

very cost-effective in the long-run Rainwater harvesting is the accumulation and

deposition of rainwater for reuse before it reaches the aquifer. Uses include water for garden, water for livestock, water for irrigation, and indoor heating for houses etc.. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used as drinking water as well as for storage and other purpose like irrigation.

Biogas Plant For Organic Waste Management Biogas is produced by anaerobic

digestion with anaerobic bacteria or fermentation of biodegradable materials such as manure, sewage, municipal waste, green waste, plant material, and crops. It is primarily methane (CH4) and carbon dioxide (CO2) and may have small amounts of hydrogen sulphide (H2S), moisture and siloxanes.

How to Operate Heavy Load?

Home appliances like dishwashers, refrigerators, and laundry machines account for about 13% of a household’s energy costs

Run your dishwasher with a full load, scraping (not rinsing) food off your dishes before loading, and letting your dishes air dry can help cut the energy use of your dishwasher.

When doing laundry, consider using cold water when possible and drying towels and heavier cottons in a separate load from lighter-weight clothes.

You can also make sure the seals on your refrigerator doors are airtight by closing the door over a piece of paper or a dollar bill so it is half in and half out of the refrigerator—if you can pull the paper or bill out easily, the latch may need adjustment or the seal may need replacing
