22% of energy now from renewable sources

Almost a quarter of the world's electricity supply is now being produced from renewable energy sources.
The proliferation of green energy production technologies has hit a significant milestone according to a new International Energy Agency report released on Thursday.

While the take-up of renewable energy sources is expected to slacken due to concerns over the cost of subsidies, more than $250 billion was invested in related technologies last year with renewable sources expected to account for up to 26% of the world's electricity production by 2020.

"Renewables are a necessary part of energy security," said executive director Maria van der Hoeve. "However, just when they are becoming a cost-competitive option in an increasing number of cases, policy and regulatory uncertainty is rising in some key markets."

Some officials, such as European Wind Energy Association deputy chief executive Justin Wilkes, have argued that the targets are not ambitious enough and that more still needs to be done to encourage the widespread uptake of renewable energy sources.

"Europe's heads of state need to agree in October on a binding 30% renewables target if real progress is going to be made to improve Europe's energy security, competitiveness and climate objectives," he said.

Yes, we need to get energy from as many sources as possible however, I have to wonder at what cost? I have heard that the production of certain energy producing tech is very polluting, I don't remember if it was solar panels, carbon fiber wind turbine props or some other tech. So are we getting cheap energy on the one hand yet more pollution on the other? I would also be curious to see how much in energy savings a wind farm generates over the lifetime of one tower vs the energy and cost required to build and maintain the structure, because I can't imagine they are cheap to build or ser...

The term is called life cycle analysis and when carried out for a wind turbine the payback is rather good in that its starts to produce net benefits after just 8months; There is a lot of Koch financed dodgy research showing massive downsides which are largely fictitious. As for Bird kills - the wind farm planning stage can eliminate most of these simply by studying where birds actually fly and avoiding them - most of the reported kills are a throw back to high speed turbines which have all but been phased out by now - slow turbines present little hazard for birds as they can fly faste...

On smaller, faster-turning rotors, bird kill can be eliminated by simply putting a cage around the fan - like on your house-hold fan. Well, Duh! Somewhere I read that pollution from the average coal-fired plant drives four species to extinction FOR EACH PLANT! Regarding my daughter, the oil and gas geologist: She says all you have to do to put her out of business is quit buying oil and gas. Petroleum geologists are used to boom-and-bust cycles. It's part of the business. She'll go into something else. The rig crews will start building foundations for windmills; the r... [More]

That's pretty good but still not enough. Have to do something more with that big fireball in the sky.

We made the change from horses to automobiles in the early twentieth century using fossil fuels. The change can be made in the early twenty first century for renewables. There are just forces at work hindering that change.

Not the least of which being every person in the world who owns a car being able to afford a new, more expensive, renewable energy one. It will happen, but it will be a very slow transition.

Automobiles were expensive at first and only the rich could afford them but Henry Ford made it affordable for the average person by coming up with the assembly line. I'm confident affordability will apply in some way today.

It will take humans several more generations to break our dependence on fossil fuels but at least we are making progress. Remember oil isn't just used as fuel. Just about everything you're looking at and touching right now has oil in it. It is the life blood of the modern world.

It doesn't mean it still can't be used to make plastics... it's just too valuable (imho) to be burning it as a fuel when it has so many other uses...

Understand though that petrol, kerosene and diesel are the light components of the oil and play little part in the formation of plastics. You need to remove them in order to obtain the chemicals needed to make plastics. As such if we continue to use plastics we will continue to need to burn light petroleum products. That presents an interesting problem in of itself since we can not afford to continue to burn fossil fuels for much longer so our dependence on plastics will also have to change. Br Cornelius
