Pessimism about renewables

in Objections, Renewables

Over on my blog, I have written a post that may be of interest to BuryCoal readers. Specifically, it is a response to the argument that society cannot depend on renewable forms of energy for the bulk of our needs because we get such a small proportion of our current needs from such sources, and there are problems with variability.

In brief, this argument is based on muddled reasoning, saying: “This is hard, therefore we cannot do it.” In reality, moving to renewables is necessary, and humanity will either accomplish it or find itself reduced to a pre-industrial mode of life.

UN climate change panel says 80 per cent of energy needs could be met by renewables by 2050

ABU DHABI, United Arab Emirates _ Renewable sources such as solar and wind could supply up to 80 per cent of the world’s energy needs by 2050 and play a significant role in fighting global warming, a top climate panel concluded Monday.

But the U.N. Intergovernmental Panel on Climate Change said that to achieve that level, governments would have to spend significantly more money and introduce policies that integrate renewables into existing power grids and promote their benefits in terms of reducing air pollution and improving public health.

Authors said the report concluded that the use of renewables is on the rise, their prices are declining and that with the right policies, they will be an important tool both in tackling climate change and helping poor countries use the likes of solar or wind to develop their economies in a sustainable fashion.

”The report shows that it is not the availability of the resource but the public policies that will either expand or constrain renewable energy development over the coming decades,” said Ramon Pichs, who co-chaired the group tasked with producing the report. ”Developing countries have an important stake in this future _ this is where 1.4 billion people without access to electricity live yet also where some of the best conditions exist for renewable energy deployment.”
