Europe's electricity could be all renewables by 2050

March 29, 2010
Wind-powered turbines cover 100 percent of the electrical needs of the 4,200 residents on the Danish island of Samso, which aims to be a model for renewable energy in Europe. Many scientists have warned that if global temperatures rise more than 2.0 C (3.6 F) by century's end, Earth's climate system could spin out of control, unleashing human misery on an unprecedented scale.

Europe could meet all its electricity needs from renewable sources by mid-century, according to a report released Monday by services giant PricewaterhouseCoopers.

A "super-smart" grid powered by solar farms in North Africa, wind farms in northern Europe and the North Sea, hydro-electric from Scandinavia and the Alps and a complement of biomass and marine could render carbon-based fuels obsolete for electricity by 2050, said the report.

The goal is achievable even without the use of nuclear energy, the mainstay of electricity in France, it said.

Over all, about 50 percent of Europe's is met with imported fuels.

Under so-called business-as-usual scenarios, that share could increase to 70 percent in coming decades, according to several projections.

The switch to renewables is more than a matter of energy security, said the report, backed by research from the Potsdam Institute for Climate Impact Research and the European Climate Forum, both based in Potsdam, Germany.

"Substantial and fairly rapid decarbonisation... will have to take place if the world is to have any chance of staying within the 2.0 degree Celsius (3.6 degree Fahrenheit) goal for limiting the effects of global warming," the report said.

Many scientists have warned that if rise more than 2.0 C (3.6 F) by century's end, Earth's could spin out of control, unleashing human misery on an unprecedented scale.

Achieving all-renewables electricity will depend less on new technology than on revamping Europe's legal and regulatory framework, the report argued: "Most of the technical components are available in principle already today."

To become a reality, such a vision will require a regional power system based on a super-smart grid and the rapid scaling up of all forms of .

It also depends on a unification of the European power market, and its integration into the North African one, allowing for free trading of between all countries, it said.

"Policies would also need to incorporate mechanisms to disincentivise construction of new fossil fuel power plants," the report added.

The European Union is on track to meet its goal of supplying 20 percent of its total energy needs from renewable sources by 2020, the European Commission reported earlier this month.

Solar energy leader Spain, along with Germany and Austria, have forged ahead of their targets, more than compensating for Italy, which has lagged behind, the Commission said.

It's a shame Europe and China are leaving us in the dust when it comes to clean energy. Thanks is part to the disasterous energy policy of the previous administration. Those who develop the new energy technology will reap the financial benefits.If we're lucky maybe we will have a breakthrough in fusion energy. Otherwise we may become dependant on foreign technology as well as foreign oil.
