Save the world, improve your lifestyle!

     Energy is what makes the world go around. Without the continuous supply of energy that most of us take for granted, things would quickly grind to a halt. We are dependent on energy for our very survival. Heating our homes, transportation, communication, health even our daily food supply, all depends on energy. But while energy delivers much that is good, it is also a primary factor in the destruction of the world's life support systems. From smog, to acid rain, to climate change, to nuclear radiation, the effects of our current energy habits are fundamentally destructive, threatening our and all future generations.

     Switching to green energy reduces your carbon footprint on the planet by an average of 6.5 tonnes of greenhouse gas emissions every year. It is equivalent to taking two cars off the road. The more people choose green energy, the more we boost our renewable energy sector. The more people switch to green energy, the more we’re saying that it's time to do something about global warming!

     Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetative cover. This wind flow, or motion energy, when "harvested" by modern wind turbines, can be used to generate electricity. The terms "wind energy" or "wind power" describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity to power homes, businesses, schools, and the like.

     Solar energy, radiant light and heat from the Sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used. Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, solar hot water, solar cooking, and high temperature process heat for industrial purposes. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

     Hydropower is one of the oldest energy sources in the world, from the first watermills to the gigantic hydro-electric power plants of today and is still one of the cheapest and globally most abundant sources of renewable energy. Once a hydroelectric complex is constructed, the project produces no direct waste, and has a considerably lower output level of the greenhouse gas carbon dioxide (CO2) than fossil fuel powered energy plants. Worldwide, an installed capacity of 777 GWe supplied 2998 TWh of hydroelectricity in 2006. This was approximately 20% of the world's electricity, and accounted for about 88% of electricity from renewable sources.
