2018-09-19: In the study, much of the assumed transformation is achieved by near-universal digitalization. The authors focus on end-use energy services, suggesting that most of these could be delivered far more efficiently using microelectronics. Household and commercial electricity use could be slashed as multiple pieces of equipment are foregone for a smart phone—whose 5 Watt power consumption would substitute for 450 Watts of consumption from cameras, calculators, TVs, game consoles, DVRs, radios, scanners, tablets, stereos, alarm clocks, GPS, weather stations, video cameras, etc. Some of these uses have already been taken over by smart phones. Moreover, the authors assume that household appliances will all be connected to the Internet of Things, to allow for their optimal operation and seamless availability for demand response.
What’s not mentioned in the Grubler scenario is that universal digitalization would require a robust, dependable electricity supply and electronic communications network. This would entail substantial new infrastructure and electricity demand to accommodate data transmission, storage, and processing for nearly every piece of equipment on Earth. It would also require a great deal of copper. And it would all have to work together seamlessly 24/7.
but... industrial uses of energy (especially for high-temperature process like cement making) will be difficult to de-carbonize, and such processes figure into nearly all supply chains. The Grubler scenario excludes aviation and shipping from consideration.
2018/04/30: key findings:
Renewable energy policies must focus on end-use sectors, not just power generation;
The use of renewables for heating and cooling requires greater policy attention, including dedicated targets, technology mandates, financial incentives, generation-based incentives, and carbon or energy taxes;
Policies in the transport sector require further development, including integrated policies to decarbonise energy carriers and fuels, vehicles and infrastructure;
Measures are needed to support the integration of variable renewable energy, taking into account the specific characteristics of solar and wind power
Achieving the energy transition requires holistic policies that consider factors beyond the energy sector itself.
The point is not that solar should not be considered, but that it should be considered, warts and all, alongside coal, nuclear and hydro with all their drawbacks. Too often, renewables' drawbacks and deficiencies are glossed over, not the least of these being that are unlikely ever to meet global energy needs
The 3D printer is a double-edged sword. It stands to transform technology and society for the better, but we also can't ignore the potential negative consequences.
Computers powered on but not in use are expected to emit approximately 20 million tons of CO2 this year, roughly equivalent to the impact of 4 million cars, according to report by 1E and the Alliance to Save Energy.
The implications of autonomous vehicles are vast, complex and difficult to predict. One thing is certain - their impact will be broad and significant.
Energy Secretary Rick Perry wants to know if wind and solar are compromising the reliability of the grid and hurting coal power. The answer lies in his home state of Texas.
Energy is often called the 'lifeblood' of civilisation, yet the overconsumption of fossil energy lies at the heart of two of the greatest challenges facing humanity today: climate change and peak oil.
The referendum shows how far Britain's economic failures have divided the country, but Brexit will only make them harder to address
Scholars are trying to figure out why we're so misinformed about the differing footprints of household appliances -- and how we might do better.

Future historians may look back on 2015 as the year that the renewable energy ascendancy began.
Energy, like roads or hospitals, is merely a means to an end.
