Ok, we're not fixing the problem, but we may be close to the point that we stop making it even worse (the supertanker has turned 90d perhaps) ....... good news, I think.

If a supertanker were to turn 90deg suddenly, it would almost certainly roll over and sink !
Researchers from Stanford University have layed out exactly how the planet could forego fossil fuel and nuclear power and adopt renewable energy across the board.
A new study by Stanford University’s Atmosphere/Energy Program makes the case that the world could be fully powered by renewable energy as early as 2050 by detailing the necessary resources for each country.
Speaking to innovation news website Co.Exist, Atmosphere/Energy Program director Mark Z. Jacobson said, "These are basically plans showing it's technically and economically feasible to change the energy infrastructure of all of these different countries."
Jacobson rejected claims that adopting renewable energy to such a wide extent would be too expensive and unreliable. “What this shows is that all these claims are mythical."

100% RENEWABLE ENERGY
For the UK it suggests 85% wind and 10% PV.
Ireland is similar about 83% wind and 12% PV.
Germany 35% wind and 62% PV (seriously?)
Spain has a broad mix, 53% solar (PV and CSP), 36% wind, 12% hydro.
US broad mix, 58% wind, 21% PV and 16% hydro.
Australia 36% wind and 53% solar.
China is quite dramatic with 64% solar and 29% wind.
India takes it even further with 77% solar and 20% wind.
African countries vary a lot, but high solar, even 90% in the Congo.

The countries with more sun appear to use more PV.

What I don't understand (and don't think Martyn did either) is why they're suggesting such a high %SP for Germany - which has a pretty similar climate to ours. It may seem like 'nit-picking' to highlight one single error but it does suggest a lack of care in preparing report.
'The golden age of coal seems to be over. Given the dramatic fall in the cost of solar and wind, the question is whether coal prices will ever recover'
The shift is dramatic. China’s coal demand has tripled since 2000 to 3.920m tonnes - half of global consumption - and the big mining companies had assumed that it would continue. The market is now badly out of kilter. Rising demand from India under its electrification drive will not be enough to soak up excess supply or replace the lost demand from China.
The share of global power from coal will drop from 41pc today to 37pc by 2020 before going into relentless decline.
While India has ambitious plans to extend power to 240m people without electricity, it is also betting heavily on low-carbon technology, aiming to install 175 gigawatts (GW) of solar, wind and other renewables by 2022.
South Asia and parts of the developing world still want to build coal plants but they are finding it much harder to obtain funding.
The World Bank and the big multilateral development agencies will not finance or guarantee new coal plants, or will only do so under stringent conditions. The Norwegian pension fund – the world’s biggest wealth fund – is divesting from coal. So is the Church of England. Private banks are becoming wary of the sector, given the tail-risk of class-action “climate lawsuits”.
China is cutting back for its own reasons, shutting down dirty home boilers to curb toxic levels of pollution in the big cities and to head off a middle class revolt.
It has installed 284 GW of hydro power over the past five years, mostly in the mountains of Sichuan and Yunnan. Solar and wind farms pepper the plains of North China. The country installed a record 23 GW of wind turbines in 2014, as much as the rest of the world put together.
