If renewable energy advocates need more evidence that solar and wind are better investments than nuclear power, a new report may offer just that.

The findings come from the newly released World Nuclear Industry Status Report 2015, which looks at global nuclear developments over the past year.

Marking a first in five decades, Japan went without nuclear power for an entire year, the report states. And three of the world’s largest economies—China, Germany, Japan—as well as Brazil, India, Mexico, the Netherlands, and Spain, now all generate more electricity from non-hydro renewables than from nuclear.

In the UK, renewable energy, including hydropower, provided more electricity output than nuclear in 2014.

Global generation from solar was up 38 percent, and wind power increased over 10 percent.

Here’s How Wind and Solar Energy are Increasing CO2 Emissions

Almost everybody today agrees that it would be really smart (if not vitally essential) that we reduce the amount of fossil carbon we release from giant, tupperware-geological structures deep inside the earth.  But how would we accomplish freeing ourselves from coal, petroleum, and gas while maintaining a dependable flow of electricity?

Mainstream environmentalists currently advocate for generating energy from wind turbines and solar arrays, whose energy comes more-or-less directly from the sun.  With solar photovoltaic, solar thermal, and wind turbines we can produce electricity without generating any carbon dioxide (once these devices have been manufactured and placed on a field or ocean somewhere).   Unfortunately, one issue with these technologies is that the energy is intermittent.  With the wind dying down and the Sun being obscured by clouds or the night, these devices only actually generate electricity a small minority of the time, let’s say generously 30% of the time.… Read the rest

Earth Getting Mysteriously Windier

Occluded Mesocyclone TornadoMason Inman writes on National Geographic:
The world has gotten stormier over the past two decades — and the reason is a mystery, a new study says. In the past 20 years, winds have picked up around 5 percent on average. Extremely strong winds caused by storms have increased even faster, jumping 10 percent over 20 years, according to the new analysis of global satellite data. The study, the first to look at wind speeds across such a large swath of the planet, bolsters some earlier findings, according to study leader Ian Young, of the Swinburne University of Technology in Melbourne, Australia. "Some regional studies had found similar results, so we suspected there may be an increasing trend," Young said.
