Mark Z. Jacobson and colleagues show that it’s technically possible for each state to replace fossil fuel energy with entirely clean, renewable energy.
One potential way to combat ongoing climate change, eliminate air pollution mortality, create jobs and stabilize energy prices involves converting the world’s entire energy infrastructure to run on clean, renewable energy.
This is a daunting challenge. But now, in a new study, Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford, and colleagues, including U.C. Berkeley researcher Mark Delucchi, are the first to outline how each of the 50 states can achieve such a transition by 2050. The 50 individual state plans call for aggressive changes to both infrastructure and the ways we currently consume energy, but indicate that the conversion is technically and economically possible through the wide-scale implementation of existing technologies.

“The main barriers are social, political and getting industries to change. One way to overcome the barriers is to inform people about what is possible,” said Jacobson, who is also a senior fellow at the Stanford Woods Institute for the Environment and at the Precourt Institute for Energy. “By showing that it’s technologically and economically possible, this study could reduce the barriers to a large scale transformation.”
The study is published in the online edition of Energy and Environmental Sciences. An interactive map summarizing the plans for each state is available at www.thesolutionsproject.org.

On Thursday, South African state-owned power utility Eskom signed a $1.5 billion loan agreement with the China Development Bank (CDB), which will form part of the financing of the Medupi Power Plant.
The signing ceremony was held at Eskom’s head office Megawatt Park in Sunninghill, Johannesburg.

Eskom’s interim group chief executive Johnny Dladla, said: “We are pleased to see the continuation of the journey of co-operation that we started with our Chinese partners last year.”
Dladla added: “The conclusion of this second loan agreement continues to demonstrate financial markets’ confidence in Eskom and South Africa notwithstanding the challenging market conditions.”
He concluded: “We are confident that the agreement will cement Eskom’s relationship with the CDB. This loan will also aide us in ensuring that we complete the Medupi project and ensure security of energy supply.”
Optimistic about the deal is Eskom’s chief financial officer, Anoj Singh: “The loan fulfils our intent to diversify Eskom’s funding sources; to date Eskom has secured 77% of this fiscal year’s funding requirement (including cash on hand), we remain resolute that we will fully execute the required funding for the year.
“We are confident that our liquidity levels and financial profile will continue to improve and stabilise.”

The affordability of South Africa’s growing fleet of renewable energy plants has been questioned on several occasions by Eskom and Public Enterprises Minister Lynne Brown also weighed in recently, telling Parliamentarians in late June that, while electricity arising from the renewables plants was costing Eskom R2.14/kWh, the utility was only able to charge consumers R0.84/kWh.
However, new analysis into the impact of renewables on Eskom’s financial position shows that the State-owned utility is, in fact, benefiting both financially and operationally from the power stations that have been brought into commercial operation as a result of the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP).
South African Photovoltaic Industry Association (SAPVIA) member Mike Levington, who is also MD of energy resources company Navitas Holdings, tells Engineering News Online that a reconciliation of Eskom’s renewables-related costs against its allowable renewables-related revenue in the prevailing tariff period shows a multibillion-rand over recovery.
Through the third multiyear price determination (MYPD3), approved payments for renewables, independent power producers (IPPs) for the four financial years, from 2013/14 to 2016/17, amounted to R38.5-billion. However, Eskom spent only R30.9-billion on renewables IPPs over the period.
“Because the entire originally planned R38.5-billion is already factored into the average Eskom sales tariff, Eskom has over-recovered some R7.6-billion through IPP tariffs since 2013/14,” Levington reveals.

How quickly the world is changing! Volvo will produce only electric vehicles from 2019. What to do with my 122s? Still enjoy driving them
The Telegraph, 6 July, 2017
France will outlaw the sale of all petrol and diesel vehicles by 2040, its new environment minister, Nicolas Hulot, has announced.
It will also ban any “new project to use petrol, gas or coal”, as well as shale oil, by that date.
The radical measures were unveiled at a press conference as part of French president Emmanuel Macron’s pledge to “make the planet great again”.
