100% renewables

100% renewables means 95% less water consumption for conventional power generation

According to a new study by Finland’s LUT University, solar PV consumes between 2% and 15% of the water that coal and nuclear power plants use to produce just 1 MWh of output; for wind, this percentage ranges from 0.1% to 14%. Under the researchers’ best policy scenario, water consumption could be reduced by 75.1% by 2030, compared to 2015 levels.

South Africa’s water-energy nexus leaves room for improvement

A team of researchers modeled the country’s energy future, finding that the drought plagued municipalities could benefit massively from large scale renewables deployment. The current reliance on coal-fired power stations causes immense water consumption, worsening the problem.

More big PV Down Under, as South Australia’s wind and solar pipeline swells to 10 GW

With the approval for a 176 MW solar farm and 66 MW battery storage facility near Murray Bridge, South Australia’s utility-scale wind and solar pipeline has reached some 10 GW.

E.on switches UK residential offering to 100% renewables

The 3.3 million U.K. households that get their electricity from E.on will receive only renewable energy. The company referred to a public opinion poll as a motivation for the move.

Washington state’s 100% renewables bill passes both Houses

Washington is looking to become the fourth state to make the move to 100% renewable electricity, with only a senate review and the hand of Governor Inslee left in the path of SB 5116.

City of Sydney sets 100% renewables target

With solar panels already installed on dozens of its buildings, the city of Sydney has upped the ante by vowing to source 100% of its electricity needs from solar PV and wind. The commitment was endorsed by city council last week, with a new 100% renewable electricity contract to be negotiated in the coming months.

More than a half million pumped-hydro sites for a world of 100% renewables

A recent Australian National University study shows that newly developed geographic information system algorithms can identify prospective sites for off-river pumped hydro projects throughout the world. The researchers, who identified around 530,000 potential sites, said pumped-hydro installations could enable large-scale energy time-shifting, as well as a range of ancillary services such as frequency regulation, which could help to integrate high levels of PV and wind into electricity systems.

Policy plan for rapid transition to 100% renewable-powered Europe handed to politicians

Politicians take note: “The energy transition is not a question of technical feasibility or economic viability, but one of political will.” Indeed, according to a new study, it is possible to rapidly transition to a Europe 100% powered by renewables and with zero greenhouse gas emissions. Solar PV leads the charge, followed by wind. Overall, eight policy recommendations have been laid out to achieve this bold goal by 2050.
