Due to the various constraints outlined above, it seems clear that renewables will not completely replace fossil fuels for existing energy needs. The transition will be partial, perhaps in the range of 30-50 per cent. Given that, in the meantime, the depletion of oil and gas resources will reduce the quantity of fossil fuels available, we may well have to rely on much less energy than is available to us at the current moment. This will put the nail in the coffin of economic growth as we know it.What also seems clear is that the energy transition would be easier if we set our sights lower and agreed to dial down our level of material consumption. The idea isn’t as far-fetched as it might seem. With a 30-per-cent drop in GDP, we would revert to a standard of living equivalent to that enjoyed in 1993, while a 50-per -cent drop would mean a standard of living equivalent to 1977. A 50-per-cent reduction in energy consumption would bring us back to the level prevailing in 1975, while an 80-per-cent reduction would be similar to the 1950s. This is hardly a return to the Middle Ages. Our parents and grandparents didn’t rub sticks together in caves!
How is the country's energy generated, and how is it consumed? This nifty Sankey diagram shows U.S. energy consumption in a simple and understandable way.
Dual use of land is resource efficient, reduces competition for land and additionally opens up a new source of income for farmers. For one year, the largest APV system in Germany is being tested on the Demeter farm cooperative Heggelbach.
In 2015, the city of Summerside, Prince Edward Island, achieved the highest level of wind power integration in North America.
According to Digiconomist’s Bitcoin Energy Consumption Index, as of Monday November 20th, 2017 Bitcoin’s current estimated annual electricity consumption stands at 29.05TWh.That’s the equivalent of 0.13% of total global electricity consumption. While that may not sound like a lot, it means Bitcoin mining is now using more electricity than 159 individual countries (as you can see from the map below). More than Ireland or Nigeria.If Bitcoin miners were a country they’d rank 61st in the world in terms of electricity consumption.
In the past month alone, Bitcoin mining electricity consumption is estimated to have increased by 29.98%If it keeps increasing at this rate, Bitcoin mining will consume all the world’s electricity by February 2020.

There are many ways to help the people of Puerto Rico, this is my humble attempt to bring Emergency power to the 70% still without power on the island. Please help me by building one of these devices and donating them to someone in need.
It is the first mainstream automaker to sound the death knell of the traditional engine, saying that starting in 2019 all the models it introduces will be either hybrids or powered solely by batteries.
As of November 2016, the American solar industry employed 260,077 workers – an increase of 24.5 percent from 2015. When you crunch the numbers, that means the solar industry is growing just shy of 17 times faster than the American economy as a whole. That’s incredible progress.
It’s important to remember: Not only is the solar industry booming – but the jobs pay well, too. As costs for materials continue to drop, solar jobs remain a well-compensated area for blue-collar workers. Bryan Birsic, CEO of Wunder Capital, said, "It seems to be one of the few areas of high-paying, blue-collar jobs – and you don't have to learn to code.”
A team of engineers led by 94-year-old John Goodenough, professor in the Cockrell School of Engineering at The University of Texas at Austin and co-inventor of the lithium-ion battery, has developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage.
Since 2007, U.S. GDP has grown by 12 percent, while energy consumption has fallen by 3.6 percent, according to the new 2017 Sustainable Energy in America Factbook, compiled by Bloomberg New Energy Finance (BNEF) for the Business Council for Sustainable Energy (BCSE).This year’s fifth edition report builds on last year’s Factbook findings that show the U.S. economy grew by 10 percent since 2007, while energy consumption fell by 2.4 percent. “In other words, energy productivity continues to improve as less and less energy is needed to fuel growth,” the authors wrote.At the same time, greenhouse gas emissions are plummeting. Total U.S. greenhouse gas emissions hit a 25-year low in 2016, down 12 percent from their peak in 2007 and 11.6 percent below 2005 levels. That puts the U.S. nearly halfway toward its Paris Agreement pledge to reduce national emissions by 26 percent to 28 percent below 2005 levels by 2025.
The ice battery is perhaps one of the stranger innovations in an exponentially growing energy storage market
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new flow battery that stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of production.
The three biggest battery power plants in the world just went live at the same time.
Coal is already fighting an uphill battle against natural gas, but the plagued commodity could come under even more pressure as solar costs continue to fall
Researchers have turned nuclear waste into something truly useful: an (effectively) eternal battery.
