Alternative energy - Pros and cons

What is alternative energy?

Alternative energy refers to energy sources from sources other than fossil fuels, viz, coal, oil and natural gas. Sometimes is also called alternative renewable energy now that almost all of them can be generated from renewable sources as opposed to non-renewable fossil fuels and not be can replenish once consumed.

Types of alternative energy and its sources

There are several types in the world. Most common and popular along with their sources are:

1 Solar energy-Sun ray;
2 Wind power - wind;
3 Wave energy - waves;
4 Bio-energy-biogas or Bio-diesel;
5. Geothermal energy underground;
6 Tidal energética-altas and low tides.

Why alternative energy?
Massive use of energy derived from fossil fuels during the entire second severely half of the 20th century has endangered the environment. Million tonnes of carbon-di-oxide-a greenhouse gas, discharged to the environment through the burning of fossil fuels are causing global warming to trap solar heat on the Earth's surface. Increase in the temperature of the Earth's surface to climate change is a matter of concern not only environmentalists but also to all the Governments of the world. Due to the increase in temperature, sea level rise and flooding a very large portion of the areas coastal causing massive devastation from coastal areas generally are highly populated. Melting the polar ice caps and glaciers due to the rise in temperature on the surface of the Earth will cause flooding of rivers and their watersheds in first instance and the drying up of rivers since then with the consequent economic disaster. Million hectares of fertile land will become a sterile. To combat this devastation resulting due to climate change world leaders are emphasizing the use of alternative energies. Use of alternative energy will reduce dependence on fossil fuels and therefore reduce the generation of di-oxide of carbon. As a result the possibility of devastation due to global warming will be reduced to a minimum.

In addition, fossil fuel non-renewable that exhausted today or tomorrow. So people are thinking about renewable energy sources to sustain the growth and development.

Benefits of alternative energy

1 Friendly environment, helps to reduce global warming.
2 It is renewable.Their sources are not exhaustible.
3 Helps reduce geopolitical tensions arising outside due to the availability of fossil fuels only in countries limited on the other hand, each country is endowed with some sort of alternative energy sources.

Disadvantages

Despite several production still of technological progress, the cost is very high that restricts its use. To date alternative energy consumption has not reached the desired level.

Conclusion

Energy alternatives is the energy of the future. Scientists from around the world must increase their greatest technological breakthrough research to make it available in affordable alternative energy enough.

A sustainable world

We are used to see how the companies seek only their own benefit, which usually correspond to leave his mark on environmental protection, but when a company is working to achieve both issues not always is news, but yes for this blog.

It is the time to start telling the achievements, make mention of companies which work for sustainability. We speak of Acciona.

Acciona is a company that is committed to sustainable development and achieves it through three fundamental aspects: innovation, environment and its Master Plan.

Innovation

Acciona spends increasingly more budget for innovation, but innovation that respects the environment hence its important presence in programs of innovation of the Government and at the same time, its presence in the European framework.

Its innovation projects focus on renewable energy, construction and sustainable transport, water technologies focusing on this very precious asset management.

Environment

One of the most important aspects in this undertaking is the introduction of the environmental variable in its decisions and operations.

Its programme "To act against climate change" is focused on the control and reduction of emissions, build mechanisms and markets of carbon, the search for new products and services, and in turn, promote awareness and awareness through social debate on climate change.

Master plan

Acciona as time-consuming working for sustainability because they are aware that things must be done in another way in which natural resources are respected, and the important thing is that it can be achieved.

Main benefits of alternative energy

With the continuous depletion of traditional energy resources, different forms of alternative energy sources are gaining ground. It is not surprising that solar energy, wind energy, geothermal energy, tidal energy, hydroelectric energy, biofuels and nuclear energy are offering a solution to meet the energy needs of households and industries.

Why alternative energy sources are becoming popular - because they are mostly renewable alternative energy resources, ensure a steady supply of energy for the present and future needs of the people.? This makes these cheaper than traditional resources, coming at a steep price tag mainly because of its limited availability and the rapid depletion of the reserves.

Thus, through the use of renewable energy from the Sun, wind, tides, biomass, etc., you can reduce on their energy bills significantly. Given that they produce clean energy, no pollution, also using those resources is a great way to go green and reduce their carbon footprint.

As alternative sources of energy are environment friendly, people who use the same does not need any additional cost for compliance with environmental rules that can be implemented in the future.

Advantages of alternative energy sources - thanks to its abundant supply of massive use, these resources not exhausted like oil and fossil fuels. Unlike the fluctuating prices of oil and natural gas, it is likely that they have a constant and stable price tag, which helps consumers to use it without having to worry about the costs of the spirals. In contrast to the large amounts of municipal solid waste that currently pollute the Earth, alternative energy offers an option for clean energy and can even process municipal waste into energy by eliminating waste.

In this way, a lot of health problems, mainly those related to respiratory diseases due to air pollution can be reduced. Another advantage of these resources is the ability of local energy production. Now you can configure the system to harness the power of the Sun, wind or tides locally, there is no need to carry the high cost of energy transport occurring miles away from where you live or dependent on imported fossil fuels from other countries.

Unlike fossil fuels which generate massive greenhouse gas emissions which in turn contribute greatly to global warming, alternative energy sources promise a clean and healthy world for present and future generations. If the switch of these resources can not be soon on a large scale, rising levels of global warming does not leave a lot to hope for future generations.

It would not be an exaggeration to say that alternative energy sources hold the key to the future.

Trends in investment in alternative energy funds

With the current trend for more respectful of the environment and sustainable energy sources, about 155 million dollars was invested in alternative energy funds last year. This Fund still does not include Spa grande, showing that the cause is growing wider and wider as time goes on.

Even large companies and powerful investors to invest their money to support the cause, it has stimulated awareness of more alternative energy sources. This year, this even is expected go higher. Among alternative energy funds, $ 13.5 million were given to companies that are developing new technologies to be more sustainable energy resources. Some 117 million dollars was invested in projects focused on renewable energy such as wind power, biofuels, solar and geothermal.

This increase in funds for alternative energy is four times higher than in 2004. Even though the global economic crisis is loomed in most companies, there was still a high share of funds for alternative energy.

Different countries are showing a lot of support in this case for more sustainable energy resources, providing greater awareness and support from all over the world. Economies such as Brazil and China contributed to the five per cent increase in the total amount of funds to hedge funds.

According to an Assistant Secretary-General and the executive director of the United Nations programme environment Achim Steiner, the economic crisis has definitely affected the clean energy campaign. This is especially true in the United States, where investments declined 2 percent. However, efforts are still just so overwhelming, especially now that sustainable energy is becoming standard.

Noteworthy are the efforts of China, which is currently the second largest wind energy market. This is in terms of new capacity, as well as photovoltaics manufacturing. Geothermal energy has been receiving more and more popular, especially in countries such as Kenya, Japan and Australia.

Even countries like Chile, Brazil, Philippines and Peru have been bringing in efforts to introduce policies and laws that promote the conservation of energy and more environmentally friendly ways of life and energy production. These countries have taken note of the alternative energy funds and have been seeing mobilization even in non-governmental organizations.

Between all energy resources, the wind was able to attract the largest number of funds for alternative energy. However, solar power had increased in terms of market share, while biofuels energy fell slightly by 9 percent.

One of the responses of the countries to the economic crisis is creating stimulus packages that have specific provisions for energy efficiency, promotion of renewable energies. These new agreements can contribute significantly to the efforts of having more clean energy. These alternative energy funds would most certainly help support the clean energy market.

Due to these efforts, it is assumed that tools of green energy prices would also fall. Solar modules, for example, expected that it would soon fall by 43 per cent in terms of price. This is because supply bottleneck have been facilitating, enabling more suppliers to produce according to the requirements of the countries. Sustainable energy unit has increased also funds alternative energy even for production companies.

This shows that the private sector is to soon to the trend. Investments were also seen in bottleneck of last year, but this year, must be at the same time and still increase significantly. Investments for sustainable energy are also one of the biggest stimulus packages in Governments around the world. Efforts have been observed and reported on different occasion. In Asia, China is still that the giant even in alternative energy funds.

There is a strong message that is beyond all these funds of energies alternatives come from all over the world. The banks are encouraged to increase its lending to the energy sector, deductions or tax exemptions are asked for funds for renewable energy sources and more efforts have been in the form of obtaining alternative energy and flow of investment funds.

The plans that are supported by funds of alternative energies are dispersed between short, medium and long term goals. As the different Governments of countries of the world continue to support the cause, we soon live in a more sustainable Earth.

Rosendale Dairy partners with UWO for New Biodigester Research

Who would have known an opportunity to turn cow poop into cash would be right under everyone’s noses? Or that the effort would not only reduce the odor of manure at an area mega-farm but could also result in a learning and research lab and public education center at the same time?

University of Wisconsin-Oshkosh Chancellor Richard Wells on Friday let out a robust laugh at the notion that all of those things could be accomplished with cow manure as the main component.

A proposal for the university and partners to build a large, wet anaerobic biodigester and biogas facility at Rosendale Dairy at Pickett in Fond du Lac County would turn cow manure into energy that could be sold to power companies.

If the proposal plays out, Wisconsin’s largest dairy farm — Rosendale Dairy — will be home to what UWO officials call one of the state’s most dynamic research, renewable energy production and public education facilities in an initiative involving the UWO’s College of Letters and Science and UW-Oshkosh Foundation.

Rosendale Dairy, owned by Milk Source, Inc., has 8,400 milking cows, which each year produce millions of gallons of manure. Last year the cows at the dairy produced enough manure to spread as fertilizer on 8,656 acres of farm land. The land-spreading has been an irritant to neighbors who claim the odor is so strong on some days that they can not venture out of doors.

The biodigester would address some of the odor problems that crop up now, a company spokesman said.

It would work by anaerobically decomposing the cow manure in the odor-controlled environment of a large digester. The decomposition of organic matter produces methane gas that is burned in engines to produce electricity that can be sold to local power companies, said Greg Kleinheinz, professor of microbiology and associate dean of the College of Letters and Science.

“One of the big benefits is that as the odor portion of the manure is essentially removed, it does not lose the nutritional value. It’s still a value to farmers on fields,” Kleinheinz said.

The digester would reduce the volume of the manure by about a third, Kleinheinz said. But because the manure contains more nutrients per pound once it’s been through the biodigester, farmers can apply less manure per acre. An added bonus is that in this form there is less chance of manure run-off from fields.

Kleinheinz called the project a great example of the University in a private partnership to help address a need. It converts manure to green energy and provides an opportunity for students to learn.

“It’s a great, big piece of research and teaching equipment for us,” Wells said. “Students will be doing all kinds of experiments to maximize the energy produced.”

The multifaceted energy plant and facility will significantly enhance UWO student learning and community outreach opportunities. It will house a public education center operated by university students and faculty. It will introduce K-12 to the science and engineering involved in harnessing renewable energy. It will be available as a remote classroom and lab for UWO students taking microbiology, biology, environmental studies and chemistry.

“Through this one proposed facility and partnership, there is the potential for much good for our campus, region and state,” Wells said.

The cost of building the system has not been released but it would be borne by the university and the foundation. The plan would be to finance the project over a 10-year period, but annual proceeds from selling energy are anticipated exceed the amount needed for loan repayment, even in the first year. The excess money would be used for scholarships and programs, according to Alex Hummel, associate director of news and public information, integrated marketing ad communication for UWO.

Milk Source, which operates several large dairies in the state, had been talking about digesters for years and had been in discussions with several potential providers. The company knew an outside source would provide one at some point, said Bill Harke, director of public affairs for Milk Source.

“The UWO proposal was almost too good to believe. This is a marvelous idea, the best plan we’ve heard,” Harke said.

About a week ago, the foundation board of directors unanimously endorsed the proposal that would form a partnership with Rosendale Dairy and the renewable energy companies Viessmann Group and BIOFerm Energy Systems of Madison.

The proposed biodigester is not the first for UWO. Viessmann and BIOFerm collaborated with the UWO foundation and the university to build a dry fermentation anaerobic facility, dedicated in May and now in operation off Witzel Avenue. It uses grass clippings, plant refuse and campus food waste to produce electricity and garbage food particles. It supplies about 10 percent of the University’s electrical needs.

Engineering and business plans for the new biodigester will be reviewed in the coming months and construction could begin in spring, with a projected startup in 2013.

35 Wind Towers Bound for Wales and Scotland

UK manufacturer of wind turbine towers Mabey Bridge is set to supply 35 Wind towers measuring in at between 65 and 70 metres in length to wind farms in Wales and Scotland.

Production of the turbines will begin in mid-February as part of Mabey Bridge’s new 24-hours-per-day work time at its new wind turbine tower manufacturing facility, a £38-million facility. Approximately 170 staff will be working on the project, including 45 new staff members and 50 that have been transferred in to meet demand from the company’s bridge-building operation.

Moving completed wind turbine tower section at Mabey Bridge Chepstow

Of the 35 towers, 14 will go to a Wales wind farm at the Pant-Y-Wal site near Rhondda in South Wales, marking the first time that turbine towers manufactured by a Welsh company will be installed in Wales.

“Quality and price were obviously key factors in awarding this contract to Mabey Bridge. However, also attractive was the fact that a key part of the wind turbines being installed at these sites will be manufactured in the UK,” said Bryan Grinham, managing director of Nordex UK.

“On site visits to Mabey Bridge we were not only impressed by the scale of the operation there but also the towers already manufactured, delivered and installed in the UK. We are excited about working with Mabey Bridge to deliver these towers on behalf of our clients Pennant Walters and Statkraft.”

Once installed—hopefully by June 2012—the turbines will generate up to 42 megawatts of electricity, enough to power 25,000 homes.

The remaining 21 towers are destined for installation in June of 2012 at the Baillie wind farm—owned by local windfarm developers and Statkraft—near Thurso on the north coast of Scotland. When installed, they will have a capacity of 52.5 megawatts and generate enough electricity to meet the energy needs of 35,000 homes.

“2011 was a challenging year for the wind turbine industry overall, with the latest available figures putting the number of new towers installed onshore in the UK last year at fewer than 25,” Mabey Bridge UK director Alex Smale said.

“Against this backdrop, the signing of a 35-tower deal with Nordex is a real boost for all the staff working at Mabey Bridge. We are very excited by the market currently and expect to make further announcements soon.”
