Harvesting Wind Power

Wind energy companies specialize in harvesting the wind’s kinetic energy and transforming it into usable electric. This is completed generally through a process that uses wind turbines to capture the energy. These turbines look like large fans. The wind turns the turbine’s fans, which then turn a shaft. This shaft provides power to a generator that can be used to power homes directly or just feed the electrical grid. Wind power has not replaced other options by a long shot, but it is gaining in popularity and feasibility mostly thanks to the diligence in research and development of wind energy companies.

Different Technology Focus

Wind energy companies range rather greatly in their focus. Although their prime mission is to provide wind energy to people, who they go about it can differ. The large, commercial size companies generally geared toward helping electric companies add to their capacity through the use of wind power. They specialize in planning, consulting, developing, research and more. Their main focus lies in creating large-scale wind farms for the collection of kinetic energy. These companies sometimes manufacturer industrial-sized turbines, create computer programs to drive their operation and more.

Smaller wind energy companies are not only available to help the big guys. There are some that specialize in the creation of smaller wind turbines for individual home or property use. Here and again, wind energy companies in this classification also design, plan and consult. In addition, they might manufacture the materials needed to create viable wind energy collectors.

Research, Development And Public Education

Wind energy companies have managed to provide about 1% of the world’s electricity. Modern turbines are rather efficient devices, but there is always room for improvement. Inasmuch, wind energy companies also work to develop new technologies that make harvesting wind power even more efficient and effective.

One of the challenges that wind energy companies are facing is the education of the masses about the potential this energy source offers. Inasmuch, they are often very vocal advocates for education about wind power and its effectiveness. Some companies also tend to have a great deal of interest in educating the public.

Wind energy companies are found in locations all over the world. These firms work to bring wind power to the masses either through large-scale projects or one home at a time.

Clean Coal Technologies For Clean Electricity

Coal-fired power plants are used by all countries in the world as one of the main source of electricity. It is estimated that 40% of global electricity is generated by coal. In countries such as China, Australia, Poland and South Africa, coal provides more than 75% of electricity. However, along with producing energy, burning coal releases harmful emissions, making coal-fired power plants one of the biggest sources of carbon emissions.

Clean coal is an umbrella term used to promote the use of coal as an energy source with technologies developed to reduce environmental impact. There are several technologies available now to reduce the environmental impact of coal energy generation. These technologies apply to various stages in the coal power plants with the purpose of reducing the amount of carbon emissions. One technology involves the chemical washing of minerals and impurities from coal. Another technology is the treating of flue gases with steam to remove sulfur dioxide. Carbon capture and storage technologies are to capture the carbon dioxide from the flue gas.

Cleaning Coal For Clean Electricity

Coal cleaning uses air and water to clean coal that was originally too dirty to burn. There are also related technologies to clean coal from acid rain, mercury and smog-causing agents. Acid rain causes sulfur dioxide at the smoke stack, thus reduce the energy efficiency of coal.

Coal Gasification For Clean Electricity

The main technology for turning coal into electricity without dumping excessive carbon dioxide into atmosphere is to “cook” the coal into a fuel gas: Carbon is removed while remaining hydrogen is burnt in a turbine. This technology uses a combination of heat, steam and pressure to turn the coal into a gas.

Through this process, carbon dioxide is being separated. Only clean hydrogen is burnt to make electricity and carbon dioxide is not released into the air. This clean coal plant could cut carbon dioxide emissions by as much as 90 percent.

Opponents note that carbon capture and storage technology has yet to be used or proven on such a large scale and that it may not be successful. There are also concerns that pumping sequestered CO2 into oil and gas wells to help make the fuels easier to pump out of the ground will lead to further consumption of fossil fuels, and CO2 emissions, thus adding to global warming.

Carbon Capture And Storage

In coal gasification process, it is theoretically possible to inject carbon captured back into the ground right on site. However, there are great concerns about the projected high costs of the process; the human health dangers of large, rapid releases of carbon dioxide back into ground and the global warming risk posed by small levels leakage over long periods.

In the past few decades, significant gains have been made in controlling sulphur dioxide, nitrogen oxides and mercury in the coal power plant. However, carbon dioxide remains a significant challenge for electrical utilities around the globe. Clean coal technologies are capable of bringing the resulting emissions of coal-fired electricity to near zero.

Fresh Water As Eco-Renewable Resources

Fresh water has become a scarce commodity in many areas already hit by climate change. Areas that have counted on spring and summer rains have been hit by drought through what should be reliably wet years of a solar minimum.

Sustainable development seeks to encourage water conservation as well as delivering sustainably collected fresh and clean water to areas where the local water supply has already been impacted by drought or pollution. Even in areas where fresh water is plentiful, preventing agricultural or sewage contamination during storms is a major and growing concern.

Oceans And Seas In Relation To Eco-Renewable Resources

The state of the oceans is inextricably linked to the state of the planet as a whole. The state of the oceans and the potential impacts of the on-going catastrophic collapse of ocean ecosystems are reaching a pitch that we haven’t seen on any other environmental issue other than the build-up of greenhouse gasses in the atmosphere.

As the polar ice caps continue to melt away into the oceans, a massive amount of heavier and very cold freshwater is being dumped into the ocean. This not only raises sea levels, but also can interfere with the currents that keep the ocean well-oxygenated and productive. The vast dead zones now spreading out from our coastlines appear to be largely the result of the vast rivers of chemicals, fertilizer runoff and sewage we’re pouring into the sea.

But most troubling of all is ocean acidification, the result of relying on the oceans to absorb the CO2 that we spew into the atmosphere. There is increasing evidence that the problem of ocean acidification is worsening rapidly, foreshadowing potential impacts that could be catastrophic for all life on Earth.

Urgency of Replacement Energy

As populations in the less developed world expanded their demands for energy, the demand on energy resources will exceed world supply within short span of time. To keep energy cheap and affordable for poorer nations who are moving into fast track, development and deployment of replacement energy must take place in the quickest possible pace.

Alternative Fusion Power

Since the beginning of the “atomic era” in the late 1940s, everyone has known about the massive potential power of fission reactions. This is what happens when an unstable element, such as radioactive or “heavy” uranium, is brought to critical mass and begins to exhibit a chain reaction. This nuclear energy can then be used to create steam and run turbines, among other things. Unfortunately the remaining waste product is plenty radioactive for thousands of years and must be disposed of at great bother and expense.

Another option is the one we are familiar with every day as the solar furnace. Light and heat from the sun is the result of a massive fusion reaction that crams hydrogen together until it forms helium, releasing massive amounts of energy in the process. Solar power is now a dream for many scientists come true. For years scientists have researched for ways to utilize this far more powerful force of physics to generate plenty of power. There is also no waste product from solar, as the energy process only produces gas which is useful with party balloons and lighter than air craft.

Hazardous Home Wastes

It is surprising just how toxic our world has become in just a few years. Synthetic chemicals didn’t even exist in any significant numbers before the turn of the 20th century. In the past, home furnishings were made of natural materials, such as carpets, pillows, curtains, bath items and towels. The things that are in the most and close contact with us each day, especially those made before 1980, were made of sustainable and renewable resources.

However, this is no longer true today. Every time when we replace our furnishing, we are trashing away materials that could contain chemicals, such as batteries and electronics. These home wastes are part of the hazardous waste brought to dumps each day.

Hazardous Waste In Overwhelmed landfills

In many countries, the problem of hazardous waste is compounded by the crisis of overwhelmed landfills. The danger from this waste getting loose in the environment is even more serious and precarious than ever. Increased danger of containment systems being breached is very real.

As pressure on forest and agricultural lands mounts, erosion due to major storm events could unleash these toxins into the ecosystems that is already fragile and damaged. Hazardous waste is becoming an acute problem beyond managment in many countries.
