Australia is sitting on top of some of the world's most potent geothermal energy sources, according to government estimates. Just one percent of the hot rock energy less than 5 km under the surface would be enough to meet the whole country's entire power needs for 26,000 years if it was tapped. So why aren't we seeing more movement on it?
An international team of scientists has found that retreating sea ice between the Atlantic and Arctic Oceans is linked to weakened air-sea heat exchange in the region. This, it warns, could result in a cooler climate in western Europe and an altered or slower Atlantic Meridional Overturning Circulation (AMOC), which would have knock-on effects for the Gulf Stream and consequently for the atmosphere.
While there is still much conjecture about the causes of some mass extinctions, it is generally believed that they can occur when a biosphere under long-term stress is subjected to a short-term shock. In 1982, Jack Sepkoski and David M. Raup published a paper identifying five mass extinction events throughout Earth's history. Now a team of researchers claims that we are entering a sixth mass extinction event, which threatens our very existence.
Following in the footsteps of Tesla and Mercedes-Benz,
Nissan is now set to become the latest automaker to offer battery packs
for stationary energy storage. Although pricing information has yet to
be provided, the Nissan product should be relatively affordable, as it
will incorporate used batteries from Nissan Leaf electric cars.
A Swiss joint venture has developed a hybrid-electric powertrain for road sweepers that's said to consume half the energy of diesel-hydraulic vehicles and reduce emissions by more than 60 percent. The modular system can also be adapted to cleaner fuel types such as hydrogen.
NASA has released a dataset setting out how rainfall and temperature patterns are likely to change in the coming decades. The data covers 21 climate models, mapping how our environment could change due to growing concentrations of greenhouse gases in the atmosphere.
A team of researchers led by Stanford University's professor Mark Z. Jacobson has produced an ambitious roadmap for converting the energy infrastructure of the US to run entirely on renewable energy in just 35 years. The study focuses on the wide-scale implementation of existing technologies such as wind, solar and geothermal solutions, claiming that the transition is both economically and technically possible within the given timeframe.
recently did it to much acclaim, and now Daimler is doing it too – the
German automotive corporation is launching its own home/business battery
energy storage system. Developed by Daimler subsidiary Deutsche
ACCUmotive, the Mercedes-Benz energy storage unit utilizes lithium-ion
batteries to store energy generated by solar cells, wind turbines or
In an effort to raise awareness ahead of World Oceans Day on June 8, Google has expanded its Street View service to let users explore a range of stunning coastal and underwater scenes.
A concept designed to rid the oceans of plastic waste is to become a reality next year. Boyan's Slat's Ocean Cleanup system is expected to be deployed in the second quarter of 2016 in the waters between Japan and South Korea. It will be the longest floating structure ever deployed in the ocean.
