Bernstein analyst: 100% renewable energy transition looking more and more feasible FacebookTwitterLinkedInEmailPrint分享Barron’s:Electricity generation is the largest single contributor to the carbon emissions that are warming the planet. It accounts for 42% of global emissions, and that share is likely to grow as transportation increasingly is powered by batteries instead of oil.As countries announce ambitious plans to wean their economies from fossil fuels, their efforts to shift how they generate electricity will determine whether they can hit those goals. The International Renewable Energy Agency (IRENA), which helps governments come up with plans to shift to renewables, has estimated that 86% of electricity can be generated with renewables by 2050.That number might seem high, but more data is now supporting the potential for an aggressive shift in power generation. In a new report, Bernstein analyst Meike Becker examined how countries can get to 100% renewable electricity generation by 2050, and the analysis has some good news about the potential for renewable generation.Becker’s report found that countries will take widely different paths to renewable generation, based on their natural resources. If coal and oil deposits determined a country’s fate in the 20th century, the force of its rivers and strength of its sunshine will likely determine its path in the 21st. Countries that generate hydroelectric power are way ahead in terms of producing clean power. Norway generates 98% of its electricity from renewable sources, largely because of hydro power. As of 2015, Brazil got 75% of its power from hydro sources. Canada relies on renewables for 67% of its electricity.But even in countries without rushing water generating much electricity, Becker sees a feasible path to renewable generation. In Belgium, for instance, hydro accounts for just 7% of generation. What’s more, Belgium depends on nuclear power for about 30% of its electricity, and the country plans to phase nuclear out by 2025. Nonetheless, Becker expects Belgium can generate at least 75% of its electricity with renewables by 2050 by relying on solar, wind and a variety of other technologies, including so-called “combined cycle gas turbines” that use gas and steam for power. The key to doing this is being able to generate and store power at times when the sun isn’t shining and the wind isn’t blowing, using batteries and technologies that can use other fuels more efficiently.The chances that countries can generate all their electricity with renewables by 2050 are “at this point very close to 100% for countries with good resources and a bit further away if conditions are less favourable,” she wrote in an email to Barron’s. Nonetheless, countries without the same resources can still generate “very high share, and usually higher than what most people currently think, I would say.”More: The path to 100% renewable power is looking more achievable
Snapchat streakers: trading 10 seconds of nudity for 5 days in paradiseStuff co.nz 13 January 2017Family First Comment: The competition promoters should be “a little more creative, and a lot more family-friendly.”A sudden burst of nude streaking around the country has been revealed as a promotional stunt organised by a self-styled social media ‘daredevil’.Up to 17,000 people around New Zealand are claimed to have signed up for the stunt and stripped off in public in the last few weeks for a chance to win a trip to Rarotonga.Photos of the streaks have peppered social media, either posted by those in the buff to prove they took part, or uploaded by startled members of the public who came across their cheeky stunts.While some saw the funny side, Family First’s Bob McCoskie said there was a time and place for nudity, and it was not on our main streets, beaches or in public where families and children could see it.“These ‘show-ponies’ should be told to cover up and go home,” he said.McCoskie said the competition promoters should be “a little more creative, and a lot more family-friendly.”READ MORE: http://www.stuff.co.nz/auckland/88373193/snapchat-streakers-trading-10-seconds-of-nudity-for-5-days-in-paradiseKeep up with family issues in NZ.
