With greater public awareness of the need for energy independence, the issue of how we can make our existing homes more resource efficient is becoming ever more critical. Residential buildings make up a large fraction of our energy needs, largely due to heating and air-conditioning.
In The Greened-House Effect , author Jeff Wilson brings his twenty-five years of construction experience and knowledge of home building to bear on making our current houses cleaner, greener, and healthier.

He presents the solutions to our building and energy problems, making them seem possible for average homeowners and small contractors by offering the right set of information, skills, and materials. More technical information is presented in sidebars and graphs, and numerous color photos illustrate the process, including:. Nuclear power is not clean, cheap, or safe. After three US-designed plants exploded in Japan, many countries moved to abandon reactors for renewables.
Heat generated from the earth s surface is called as geothermal heat. This form of energy is the clean and sustainable. They can be from the shallow ground to hot water and hot rock found beneath the earth surface, also found extremely deeper to the extremely high temperatures of molten rock called magma. Usually the heat pumps have With all the possible advantages there is a con with the geothermal heat that in the extreme conditions it can also cause earthquake. The sustainability of geothermal energy is highly dependent on proper management of the reservoirs.
With these minor issues, Geothermal is having the massive worldwide potential of 2 terawatts TW.
It also gives the less fluctuation cost with stable electricity cost. The flowing water energy is converted to electricity in the hydropower plants. Most commonly the dam water is used. Flowing water through turbines ii used for the power generation. Work is going on to design the power plants in such a way that it causes minimum affect to the river water. Sometimes this power plant hinders the life of the fishes so different approaches are employed such as fish ladders and improved turbines to assist the migration of fishes and lower their death rate.
Sun is the ultimate and the natural source of energy for all the available fuels. From thousands year suns ray has been used for providing warmth and serving the purpose of drying. The solar system don not produces air pollutants and they also have the minimum impact on environment. There is quite variation in the amount of sunlight that reaches the earth surface depending on the location, time of day, season of the year and weather conditions.
Various solar technologies are there that directly tap the infinite power of sun and which is further used to produce heat, light and power. Solar Thermal electricity not only provides the heat but also generates the electricity. Solar energy can be converted to electricity in two ways i. PV systems are often used in remote locations that are not connected to the electric grid. They are also used to power watches, calculators, and lighted road signs. Solar Power Plants indirectly generate electricity when the heat from solar thermal collectors is used to heat a fluid which produces steam that is used to power generator.
Tidal Power or Tidal energy is the form of energy that converts the energy generated through the tides into the useful form mainly electricity. Tidal energy is not so common as compared to other forms of renewable energy. Tidal steam generators are there that converts the energy into electricity. Same kinetic energy is converted into electricity.
The energy form the tidal is could decrease the usage of nuclear power if associated to the radiation risks. Nearly 3, terawatt-hours energy is produced by tidal power yearly. Although not used widely, tidal power can be used in the future for the electricity generation.
Tidal power has less availability as compared to other renewable sources due to the high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities. There has been many technological developments and improvements which has resulted in the higher availability of the tidal power plants. Many revised design e. This form of energy is produced when the electricity generators are placed on the surface of the ocean.
Output of the energy is calculated by the wave height, wave speed, wavelength and the water density. Energy generated by waves is converted into electricity through the electric generator. Wave movement is harnessed and converted to electricity. Depending on the method used for the capture of wave energy, it can be characterised into hydraulic ram, elastomeric hose pump, and pump to shore, hydroelectric turbine, air turbine and linear electric generator.
Being a renewable source of energy, wave energy can have certain disadvantages to the marine animals. One of the alternatives used against fossil fuels. Wind power is plentiful, renewable, widely distributed, clean without any emission of greenhouse gases.
The New Net Zero
It often uses less land with less water consumption. The rotor is connected to the main shaft, which spins a generator to create electricity. This form of energy is used for the electricity generations which either uses the warm surface water or boiling the sea water turning it to the turbine further activating the generator. There are no fuel costs, no harmful gases are produced but it may cause noise pollution to the surrounding people.
With the advancement in technology, the wind energy generated from the wind turbine can be used for the electricity generation. Wind energy doesn't contaminate the air like power plants that depend on burning of petroleum products, for example, coal or gaseous petrol. Wind turbines don't deliver air discharges that lead to medical issues like asthma or make corrosive rain or nursery gasses.
By using the cells, Solar PV systems convert the sunlight into electricity. The cell system comprises of one or two layers of a semi conducting material mainly Silicon. Electric field is generated as soon as the light shines on the cells. In the event that electrical conveyors are joined to the positive and negative sides, framing an electrical circuit, the electrons can be caught as an electric current - that is, power. The performance of a Solar cell is measured depending on it productivity to transform daylight into power.
Low efficiencies imply that bigger clusters are required, and that implies higher cost. Hybrid renewable energy Sources. Some common configurations used in the HRES are:. For ensuring continuous supply of power to the load there has to be critical storage technology.

There are many types of energy storage that can be used in hybrid renewable energy system for example, compressed air energy storage CAES , Pumped hydro storage PHS , hydrogen fuel cells, flywheels, supercapacitors, superconducting magnetic energy storage SMES and batteries. Thermal energy and mechanical energy are the two energy forms produced by the ocean energy. Thermal energy is produced by the suns heat whereas the mechanical energy produced by the tides and waves.
The energy is carried by ocean waves, tides, salinity, and ocean temperature differences. Oceans carry an incredible amount of power and energy potential with the potential to develop 20,—80, terawatt-hours TWh of electricity generated by changes in ocean temperatures, salt content, movements of tides, currents, waves and swells. Despite the fact that the marine vitality innovation has not completely conveyed on its potential, there have been, in late time, various ranges in marine vitality that has commenced.

This vitality can be saddled to create power to control homes, transport and ventures. Sea vitality has the capability of giving a significant measure of new sustainable power source around the world. Oftenly called as efficient energy, Energy Efficiency aims to reduce the energy required for proving the products and services. Nowadays, with the so many innovations and advancement in technologies it is becoming essential to make the proper usage of energy which is achieved by energy Efficiency. Energy Efficiency helps to maintain the environment by protecting the air and preventing the change of climate.
Energy efficiency plays an important role in the balancing of the economy. Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy policy and are high priorities in the sustainable energy hierarchy. Likewise saving the energy can give influence and empower home and entrepreneurs to save the money by putting away energy from the matrix when electric rates are low, and in addition utilizing the stored energy throughout the day. Renewable Energy Options for Homeowners, 3rd Edition.
