Transforming homes into power stations – how Sweden is disrupting energy production

  • 54% of Sweden’s power comes from renewables and this energy is increasingly local.
  • Smart grids are switching Swedish homes from energy consumers to power-making ‘prosumers.’
  • Local ‘district heating’ plants use excess heat to warm the majority of Swedish homes.
  • Sweden tops the World Economic Forum’s Energy Transitions Index

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.

As well as targeting 100% renewable electricity production by 2040, the country is transforming homes into highly efficient ‘prosumers’ – buildings which both produce and consume the vast majority of their own energy.

Fossil fuel drilling could be contributing to climate change by heating Earth from within

Fossil fuel drilling could be contributing to climate change by heating Earth from within

Almost all scientists agree that burning fossil fuels is contributing to climate change. But agreement is less clear cut on how exactly it’s influencing rising global temperatures.

The world is now 1°C warmer than it was in pre-industrial times. Is this solely down to emissions of greenhouse gases such as CO2? Meteorologist Hubert Lamb, regarded as the father of modern climatology, argued that CO2 levels alone couldn’t account for all of the global warming that’s been observed.

His attention turned instead to the role of thermal emissions. Burning fossil fuels doesn’t just produce greenhouse gases, it also generates a lot of heat, which leaks out to the atmosphere. Nuclear tests and volcanic eruptions are some examples of other large heat sources.

Chart shows the surprising links between faith and evolution and climate denial

imrs

For a long time, the discussion about the relationship between religious beliefs and the rejection of science, has been pretty confused, especially its two most prominent U.S. incarnations, evolution denial and climate change denial.   Continue reading… “Chart shows the surprising links between faith and evolution and climate denial”

China may get over its coal addiction faster than anyone thought

Beijing’s air quality is thanks in large part to coal-burning.

Lead writers of Citigroup’s new note attacks “one of the most unassailable assumptions in global energy”—the forecast that China’s coal consumption will grow wantonly over the next two decades. By extension, it challenges apocalyptic climate change forecasts.

Stephen Hawking joins international think tank to defend humanity from futuristic threats

Stephen Hawking wants to stop the rise of the machines.

Stephen Hawking turned  71 on January 8th and has joined the board of an international think tank devoted to defending humanity from futuristic threats. The newly founded organization, the Cambridge Project for Existential Risk, researches existential threats to humanity such as extreme climate change, artificial intelligence, biotechnology, artificial life, nanotech, and other emerging technologies. Skype cofounder Jaan Tallinn and Cambridge professors Huw Price and Martin Rees founded the project in late 2012.

Scientists said on Tuesday that they had discovered the world’s first hybrid sharks in Australian waters, a potential sign the predators were adapting to cope with climate change.
The mating of the local Australian black-tip shark with its global counterpart, the common black-tip, was an unprecedented discovery with implications for the entire shark world, said lead researcher Jess Morgan…
