Green Strategies written by azuaina at Sunday, 9 March 2014 & got 0 Comments What Is Green Technology: Strategies
Green technology is a relatively new field that has grown quickly as people have become aware of their detrimental effects on the environment, including global warming and the greenhouse effect. It is a wide-encompassing field and sometimes a politically controversial one. Green technology is one of the fastest growing employment sectors and is surely much more than a passing trend.The types of green technology range from very simple tasks that can be performed in your home to highly specialized systems.
Recycling
Rather than throwing all of your trash into a landfill, recycle objects made of glass, metal, paper, and plastic. These materials are reusable and by recycling them, you can help prevent the further depletion of the earth's resources. Contact your local government about recycling programs in your area.
Environmental Remediation
Another aspect of green technology involves removing contaminates from the soil, air and water. These processes range from chemical to biological. Industry is responsible for much of the contamination and the government has enforced strict regulations to curb it.
Renewable Energy Sources
The world can't rely on fossil fuels forever to power homes, automobiles and factories. Green technology includes the conversion of renewable resources, such the sun's light, wind and water to energy that we can use. Solar panels, wind turbines and geothermal wells are all examples of technological innovations that can replace the need for coal and oil.
Alternative Fuels
Aside from harnessing nature's energy, scientists are also looking into other alternatives to fuel, which include hydrocarbons, fuel cells, and the highly debated concept of clean coal. The clean coal concept is driven by the goal to lessen the impact of carbon dioxide emissions on the environment from the burning of coal as an energy source. The desired effect is either no carbon dioxide emissions or to reduce the emissions to such a low amount that the impact becomes insignificant. Another alternative fuel goal is that someday, hopefully soon, automobiles will not need to run on gasoline.
Cradle to Cradle
This term refers to the recycling of manufactured products from renewable materials that can be reused again and again, rather than going from cradle to grave, used once and then disposed.
Sustainable Development and Building
Designers and building owners can take many steps to make a building "green". Some of these strategies include properly siting the building to take advantage of natural conditions including solar orientation, using recycled or environmentally friendly building materials and reducing suburban sprawl. Obviously, any type of construction is inherently detrimental to the environment, but with careful planning it is possible to reduce any negative impact.
Green nanotechnology
This quickly growing field of science operates on the scale of one billionth of a meter, or a nanometer. Materials are manipulated in ways that will transform the manufacturing industry. Green nanotechnology involves principles of both chemistry and engineering.

How can we live lightly on the Earth and save money at the same time? Staff members at the Worldwatch Institute, a global environmental organization, share ideas on how to GO GREEN and SAVE GREEN at home and at work. To learn more about Worldwatch's efforts to create am environmentally sustainable society that meets human needs, sign up here for weekly e-mail updates.
Climate change is in the news. It seems like everyone's "going green." We're glad you want to take action, too. Luckily, many of the steps we can take to stop climate change can make our lives better. Our grandchildren-and their children-will thank us for living more sustainably. Let's start now.
We've partnered with the Million Car Carbon Campaign to help you find ways to save energy and reduce your carbon footprint. This campaign is uniting conscious consumers around the world to prevent the emissions-equivalent of 1 million cars from entering the atmosphere each year.
Keep reading for 10 simple things you can do today to help reduce your environmental impact, save money, and live a happier, healthier life.

What is green energy? written by azuaina at & got 0 Comments 
In the past three decades, research and development in green energy has exploded, yielding hundreds of promising new technologies that can reduce our dependence on coal, oil, and natural gas. But what is green energy, and what makes it a better option than fossil fuels?
Green energy defined
Green energy comes from natural sources such as sunlight, wind, rain, tides, plants, algae and geothermal heat. These energy resources are renewable, meaning they're naturally replenished. In contrast, fossil fuels are a finite resource that take millions of years to develop and will continue to diminish with use.
Renewable energy sources also have a much smaller impact on the environment than fossil fuels, which produce pollutants such as greenhouse gases as a by-product, contributing to climate change. Gaining access to fossil fuels typically requires either mining or drilling deep into the earth, often in ecologically sensitive locations.
Green energy, however, utilizes energy sources that are readily available all over the world, including in rural and remote areas that don't otherwise have access to electricity. Advances in renewable energy technologies have lowered the cost of solar panels, wind turbines and other sources of green energy, placing the ability to produce electricity in the hands of the people rather than those of oil, gas, coal and utility companies.
Green energy can replace fossil fuels in all major areas of use including electricity, water and space heating and fuel for motor vehicles.
Types of green energy
Research into renewable, non-polluting energy sources is advancing at such a fast pace, it's hard to keep track of the many types of green energy that are now in development. Here are 6 of the most common types of green energy:
Solar Power - The most prevalent type of renewable energy, solar power is typically produced using photovoltaic cells, which capture sunlight and turn it into electricity. Solar energy is also used to heat buildings and water, provide natural lighting and cook food. Solar technologies have become inexpensive enough to power everything from small hand-held gadgets to entire neighborhoods.
Wind Power - Air flow on the earth's surface can be used to push turbines, with stronger winds producing more energy. High-altitude sites and areas just offshore tend to provide the best conditions for capturing the strongest winds. According to a 2009 study, a network of land-based, 2.5-megawatt wind turbines in rural areas operating at just 20% of their rated capacity could supply 40 times the current worldwide consumption of energy.
Hydropower - Also called hydroelectric power, hydropower is generated by the Earth's water cycle, including evaporation, rainfall, tides and the force of water running through a dam. Hydropower depends on high precipitation levels to produce significant amounts of energy.
Geothermal Energy - Just under the earth's crust are massive amounts of thermal energy, which originates from both the original formation of the planet and the radioactive decay of minerals. Geothermal energy in the form of hot springs has been used by humans for millennia for bathing, and now it's being used to generate electricity. In North America alone, there's enough energy stored underground to produce 10 times as much electricity as coal currently does.
Biomass - Recently-living natural materials like wood waste, sawdust and combustible agricultural wastes can be converted into energy with far fewer greenhouse gas emissions than petroleum-based fuel sources. That's because these materials, known as biomass, contain stored energy from the sun.
Biofuels - Rather than burning biomass to produce energy, sometimes these renewable organic materials are transformed into fuel. Notable examples include ethanol and biodiesel. Biofuels provided 2.7% of the world's fuels for road transport in 2010, and have the potential to meet more than 25% of world demand for transportation fuels by 2050.
