Ocean Provides Heat To Low-Income Residents

This Town Is Using The Ocean To Provide Heat To Low-Income Residents
July 24, 2014 - When most people think of harnessing renewable energy from the ocean, the gigantic spinning blades of offshore wind farms are probably the first thing that come to mind. Or maybe it’s gracefully bobbing buoys capturing wave energy or dams that skim power off rushing tides. Very few people, however, think of the oceans as a vast source of renewable heat that can be used to keep homes warm and showers steaming. But that’s exactly what a growing number of seaside towns in northern Europe are doing, despite having some particularly chilly ocean water.

It should perhaps come as no surprise that the ocean can be used to climate control our homes. After all, the Earth’s oceans essentially climate control the entire planet. read more>>>

Saving $$$ Solar Energy Project

New solar energy project at Utah Olympic Oval will save $$$
July 21 2014 - A new solar energy project at the Utah Olympic Oval announced Monday is expected to shave about $100,000 off the speedskating facility's annual $750,000 power bill.

Much of the $1.4 million cost of the solar paneled canopies being installed above parking spaces is being paid for through a $564,000 grant from Rocky Mountain Power and $200,000 from Salt Lake County.

"We know it can't only be us looking at keeping the facility going," said Colin Hilton, president and CEO of the Utah Olympic Legacy Foundation responsible for maintaining 2002 Winter Games competition sites.

Hilton said the project will help extend the life of the foundation's endowment, established with profits from the 2002 Olympics, by reducing the subsidy needed by the oval. read more>>>


Own Solar Power Grid Serves Entire Village

A village in India now runs entirely on its own solar power grid
22 July 2014 - On Sunday, the eldest resident of Dharnai, India, flipped a switch and the village officially joined the age of electricity. But Dharnai, in India's northeastern Bihar state, did more than join a reliable energy grid — it became India's first village powered entirely by solar electricity. A few months ago, Greenpeace and two other NGOs that work in the area (BASIX and CEED) started building a solar power micro-grid to serve the village, and after a few months of testing, the autonomous 100 kilowatt system officially went online this past weekend.

The Dharnai grid serves about 450 homes, housing 2,400 residents, Greenpeace says, as well as roughly 50 businesses, streetlights, water pumps, two schools, health care center, and other public and private ventures. It has a battery to store excess electricity, for use during the sunless hours. read more>>>

Climate Change Mega-Map

New mega-map details all the ways climate change will affect our everyday lives
18 Jul 2014 - From flood barriers to fish stocks, a new super-graphic from the Met Office and the UK Foreign and Commonwealth Office shows how climate change is likely to alter human activity.

Looking at where our food comes from and how countries interact through travel and trade, it makes for a stark visualisation of what different regions can expect as climate change kicks in.

'reef effect' of Offshore wind farms

Offshore wind farms create 'reef effect' perfect for marine wildlife - especially seals
21 July 2014 - Wind farms and wildlife do not always go together: the giant turbines have been accused of luring species to their death, and the noise they generate can drive away certain marine mammals.

But wind farms have an unexpected benefit if you happen to be a harbour seal hunting for food in British waters, according to a new study. They are a magnet for hungry seals eager to take advantage of the fact that fish and crustaceans tend to cluster on the structures – which become artificial reefs for marine life over time.

Offshore wind farms can be fertile feeding grounds for seals who choose to seek them out – concludes the study, by an international team of researchers from Britain, Holland and the US, published yesterday in Current Biology Journal.

This is because the presence of a hard structure beneath the waves attracts barnacles and other crustaceans, and, in turn, fish. Dr Deborah Russell, a research fellow at the Scottish Oceans Institute at the University of St Andrews, explained how the “reef effect” attracts seals. “Things like barnacles and mussels will settle on hard structures and then that in turn will attract other marine species and it builds up over time.” read more>>>

Guess who's winning the energy efficiency World Cup

Certainly not the U.S. as we allowed the special interests to block the growth into alternatives some forty years back and since, only excuse they can muster and finance now is 'climate change denial', as at the same time we started shipping off our innovative and experienced trades that had built an economic engine envied by most who now have those trades!

The International Energy Efficiency Scorecard
The International Energy Efficiency Scorecard ranks the world's largest economies on their energy efficiency policies and programs. The rankings include Australia, Brazil, Canada, China, France, Germany, India, Italy, Japan, Mexico, Russia, South Korea, Spain, the United Kingdom, the United States, and the European Union.

Thirty-one different energy efficiency indicators have been analyzed for each economy ranked in the report. The rankings are determined by scoring out of 100 possible points. Points can be earned in four different categories, including buildings, industry, transportation, and national effort, which measures overall or cross-cutting indicators of energy use at the national level. read more>>>
