Power generation could take a big hit from climate change

CBC News / 04 January 2016

russia-societyClimate change could lead to significant declines in electricity production in coming decades as water resources are disrupted, said a study published on Monday.

Hydropower stations and thermoelectric plants, which depend on water to generate energy, together contribute about 98 per cent of the world’s electricity production, said the study published in the journal Nature Climate Change.

Shifts in water temperatures, or the availability of fresh water due to climate change, could lead to reductions in electricity production capacity in more than two thirds of the world’s power plants between 2040 and 2069, said the study from an Austrian research centre.

Extreme weather poses increasing threat to power grid

phys.org / Holbrook Mohr, Garance Burke / 22 December 2015

extremeweather and gridWhen Hurricane Katrina’s punishing storm surge plowed ashore, it swamped seven of Coast Electric Power Association’s substations, vital to powering thousands of Mississippi homes and businesses. The facilities have long since been repaired, but a decade after the storm they remain at the same elevation, and just as vulnerable to catastrophic hurricanes.

Such storms are a growing threat. An Associated Press analysis of industry data found that severe weather is the leading cause of major outages on the nation’s power grid. The number of weather-related power outages has climbed over the last decade, with the greatest spikes in 2008 and 2011, according to the AP analysis and independent studies.

World’s energy systems at risk from global warming

The Guardian / Fiona Harvey / 01 October 2015

NYC SandyThe world’s energy infrastructure is at risk from the extreme weather expected to result from climate change, a group of prominent energy companies has warned.

Energy systems, including fossil fuel power stations, distribution grids, and the networks that reach to people’s homes, are all at risk from effects such as flooding, severe storms and sea level rises, according to a new report from the World Energy Council, which brings together energy companies, academics and public sector agencies.

When energy systems fail, the knock-on effects on other aspects of modern infrastructure – from water and sewage to transport and health – can be catastrophic.

Experts point to the effects of Hurricane Sandy in New York to show that these effects are not limited to the developing world, where most of the serious consequences of climate change are expected to wreak havoc, but will be felt even in the most modern of cities.

U.S. electricity facilities less than 4′ above local high tide

Union of Concerned Scientists / 2014

Map-US-Electricity-Facilities-Less-Than-Four-Feet-Above-Local-High-Tide_Full-Size

Nearly 100 electricity facilities in the contiguous United States, including power plants and substations, are within four feet of high tide — and are therefore vulnerable to rising sea levels.

Brazil’s most populous region facing worst drought in 80 years

BBC News / 24 January 2015

Sao Paulo stateBrazil’s Environment Minister Izabella Teixeira has said the country’s three most populous states are experiencing their worst drought since 1930.

The states of Sao Paulo, Rio de Janeiro and Minas Gerais must save water, she said after an emergency meeting in the capital, Brasilia.

Ms Teixeira described the water crisis as “delicate” and “worrying”.

Industry and agriculture are expected to be affected, further damaging Brazil’s troubled economy.

The drought is also having an impact on energy supplies, with reduced generation from hydroelectric dams.

The BBC’s Julia Carneiro in Rio de Janeiro says Brazil is supposed to be in the middle of its rainy season but there has been scant rainfall in the south-east and the drought shows no sign of abating.

Peak oil and peak water explained

Truthloader / 23 July 2013

Peak oil is something you often hear, but have you ever heard of peak water? Water shortages, and more specifically, fresh water shortages, are likely to become more commonplace in the future. Truthloader took a look into the two terms and what they mean.

The Transition Framework

Inner Transition is occasionally overlooked in favour of more immediately ‘practical’ undertakings, reinforcing an observed and acknowledged division in many Transition Initiatives between “doers” and “talkers”, but for Transition Initiatives looking to foster a kind of community resilience that is equitable, inclusive, nimble, responsive, caring, and cohesive, Inner Transition efforts are a necessary place to start.
