The surface of the Earth receives an amount of solar energy equivalent to roughly 10 000 times the worlds energy demand. Of course there isn’t always sunlight, but the solar panels can store the energy, and they are getting better and better at it. A solar panel converts one sixth of the sunlight into electrical energy. Although they also are getting able to turn more and more of the sunlight into energy, they are already so efficient that space isn’t much of an issue anymore. The area of solar cells needed to supply a family with electricity is usually much smaller than the roof of their house. And when including the land required for mining and excavation of coal, CPS-plants (power-plants that rely on solar energy) are more space-efficient than power-plants fueled by coal. Solar power is roughly fifty times as space-efficient as growing crops for bio fuels. And that’s just with the technology that currently is commercialized.

New findings from Dr Anthony Patt of the International Institute for Applied Systems Analysis in Africa shows that the proposed supergrid that could power all of Europe with renewable energy only would need around £50 billion of government funded money to become a reality.

The £50 billion government investment would, according to Patt, convince private companies that the supergrid idea is both “feasible” and “attractive”, the Guardian reports.

“In the long term, such a plan, combined with strings of windfarms along the north Africa coast, could “supply Europe with all the energy it needs”.

He said technological advances combined with falling costs have made it realistic to consider north Africa as Europe’s main source of imported energy.

“The sun is very strong there and it’s very reliable. There is starting to be a growing number of cost estimates of both wind and concentrated solar power for North Africa….that start to compare favourably with alternative technologies. The cost of moving [electricity] long distances has really come down.”

Sweden might be the host for Europe’s largest wind farm if the Swedish government approves the proposed plans. The wind farm will be located in Markbygden near Piteå in northern Sweden and will have a total of 1,101 wind turbines.

“This would be Europe’s, if not the world’s, biggest wind farm,” Caj Noren, a spokesman for the board, told AFP. Construction could begin in two-and-a-half years and would be completed after about a decade, Noren said.

Once constructed the wind farm will produce between 8 to 12 terawatt hours per year and would alone meet Sweden’s national wind power target to reach 10 terawatt hours by 2015. The wind farm is expected to cost about 55 billion Swedish Kronor (around $6.9 billion or €4.5 billion) to construct.

The Swedish right-wing government recently announced that they will reverse a nearly 30-year-old ban on building nuclear power plants. Its madness when we can get cheap, clean renewable energy and at the same time create thousands of new jobs from wind farms like this one.

New research from the Helsinki University of Technology’s Advanced Energy Systems in Espoo, Finland, shows that with the help from global cooperation and investment renewable energy will “exceed all previous estimates.”

According to the new findings renewable energy technologies like wind and photovoltaics could supply 40% of the world’s electricity by 2050. But this could only become a reality if the renewable technology is backed up by adequate financial and political support. If not, the renewable share is likely to hover somewhere below 15 percent.

“Our findings demonstrate that with global political support and financial investment, previous notions that the potential for renewables was in some way limited to a negligible fraction of world demand were wrong,” Peter Lund from the Helsinki University of Technology’s Advanced Energy Systems said. “If we prioritize and recognize the value of renewable energy technologies, their potential to supply us with the energy we need is tremendous.”

Previous projections have put the renewable share at only 12% by 2030.

Sölvesborg, a small village near the coast located in southern Sweden, was first in the world with sea-based wind power. And now it might become the place for Sweden’s and northern Europe’s largest offshore wind farm.

The renewable energy companies Vingkraft AB and Eolus Vind AB wants to construct 500 wind turbines in the sea outside of Sölvesborg by 2014-2019. Once completed the wind farm will supply 5-7 TWh of electricity every year. That is equal to the amount of electricity the now decommissioned Swedish nuclear plant Barsebäck generated every year.

Although the proposed wind farm have a long way to go and many different instances to pass, such as the military, before getting approved the local politicians and people in the region are excited. The politicians believe the wind farm will create thousands of new jobs in the region and even act as a way to attract more tourists.

The wind farm is expected to cost 50 billion Swedish kronor, equal to around €4.5 billion.

The Guardian reports that in the Andalucian deserts, 20 miles outside Seville, the Spanish company Abengoa will soon open up the world biggest solar power tower.

Over 1,000 mirrors, each “about half the size of a tennis court”, will be used to reflect sunlight to “superheat” water at a central tower. Once completed, at a cost of €80 million, the energy plant will generate 20MW of electricity to 11,000 Spanish homes.

“Concentrated solar power (CSP) technology, as it is known, is seen by many as a simpler, cheaper and more efficient way to harness the sun’s energy than other methods such as photovoltaic (PV) panels. But CSP only works in places with clear skies and strong sunshine.

The Andalucian deserts are an ideal location, and Spain hopes the PS20 plant will enable it to take advantage of its huge solar resource and lead the field in CSP technology.

“The radiation hitting the earth is 10,000 times the consumption of energy,” said José Domíngues Abascal, chief technology officer at Abengoa, the Spanish energy company behind the plant. “There is great potential in solar energy.””

According to the U.S. Energy Information Administration renewable energy now accounts for more than 10% of the domestically-produced energy in USA during the first half of 2008. Most of the energy comes from renewable energy sources such as biomass/biofuels, geothermal, hydropower, solar and wind.

This number can be compared to the 11.98% of energy that nuclear energy contributes to in USA. According to the SUN DAY Campaign the total consumption of nuclear power dropped by 1% during the first half of 2008 while the renewable energy increased by 5%.

Five French wind farm projects, totalling 77MW capacity came online in February 2008. Project France phase-2 was a €115 million project constructing a total of 42 turbines. This challenge was undertaken as a joint venture by EOLE-RES S.A, a French wind park developer, and Renewable Energy Systems of the UK.

Mott MacDonald Ltd, a well renowned Global engineering consultancy, was appointed as Lenders and Owners Engineer for the project, which spanned three regions of France. In charge of due diligence as well as Owners’ engineer work for the project, Mott MacDonald was also present throughout the construction phase. Ron Donnelly of Mott MacDonald explained the increase in wind farm developments recently was “due to high oil prices there is more motivation for people to try to meet the low carbon agenda…investments in wind farms are becoming much more popular.”

The French President Nicolas Sarkozy earlier this summer launched, with the support of EU, a new Mediterranean union with the aim to “tackle issues such as regional unrest, immigration to pollution.”

The new international body will include 16 non-EU states from around the Mediterranean and all 27 EU member states. The union will focus on dealing with energy, security, counter-terrorism, immigration and trade. The union will include 756 million people from Western Europe to the Jordanian desert.

Some say that the Union was launched mainly because Nicolas Sarkozy wanted to “exchange” nuclear power expertise with North African gas reserves. Nicolas Sarkozy on the other hand says the union is supposed “to ensure the region’s people could love each other instead of making war.”

But some people are more positive and hope the union is the first steps towards large scale solar plants in northern Africa with focus of generating green and renewable electricity to Europe.

The statistics are in for the first half of 2008 and they show that USA, for the first time, generated more wind energy than Germany. This “milestone” wasn’t expected to be reached until late 2009.

Germany still has more wind turbines than USA and is able to generate 22,000 – 23,000 megawatts of power compared to USA’s capacity of about 18,000 megawatts.

But Randall Swisher, the executive director of the American Wind Energy Association, said that “the difference is that because the winds are so much stronger here in the U.S. we are actually providing more wind-generated electricity than Germany.” He also said that the US “wind energy capacity is growing faster than anyplace else.”

This is great news but USA is still far behind everyone else in terms of green renewable energy, especially wind energy.
