Tidal power to the people | Letters

Guardian - Renewable Energy - Thu, 07/05/2018 - 16:50
Alicia Hull on tidal energy being more efficient than nuclear, Liam O’Keeffe underlines its benefits, and Sue Roaf shines a light on solar

In his letter, Jim Waterton (30 June) protests too much. If tidal energy cannot be allowed without the possibility and costs of storage being certain, how is it that nuclear has been allowed when the costs and feasibility of storing the used fuel for countless lifetimes is equally unknown and likely to be much higher?

He describes tidal energy as intermittent, when it is regular and very suitable as a base power source. In contrast, he describes nuclear power as consistent when this is far from the truth. Quite apart from their hopeless record on delivery dates, rising costs and concern that they will work, they’re also offline from time to time. The station at Sizewell is offline for maintenance for five to six weeks every 18 months. By November last year there had been 16 planned outages. But there had also been unplanned outages when dangerous faults have been identified.

Declare energy independence with carbon dividends | Joseph Robertson

Guardian - Renewable Energy - Wed, 07/04/2018 - 10:00

A carbon tax and dividend system could usher in an era of clean energy independence

Taking action on climate is about a lot more than our energy economy. Climate disruption is the leading threat to our built environment, an accelerant of armed conflict, and a leading cause of mass migration. Its effects intensify and prolong storms, droughts, wildfires, and floods — resulting in the US spending as much on disaster management in 2017 as in the three decades from 1980 to 2010.

Guardian - Renewable Energy - Wed, 07/04/2018 - 05:00

Tidal power is the only renewable source derived from the moon. Now an extraordinary array of devices promise to unlock this vital energy potential

Using giant kites, blades and paddles, and mimicking pogo sticks, blowholes and even the human heart, groups around the world are on the cusp of harnessing the colossal power of the oceans.

The challenge is huge - seas have been battering coasts and sweeping sailors to their doom for millennia - but so is the prize: huge amounts of clean, reliable and renewable electricity for an energy-hungry world.

Solar Developers May Be Able to Avoid Solar Tariffs Under New IRS Tax Credit Guidance

Renewable Energy World - Mon, 07/02/2018 - 19:27

At the end of June, the U.S internal revenue service (IRS) clarified the rules surrounding when solar developers are allowed to take the 30 percent Investment Tax Credit (ITC) for solar projects. The 30 percent tax credit is available until the end of 2019, at which time it will step down incrementally for 4 years, finally settling at 10 percent.

Energy Storage Saves the Day During Heat Wave in Vermont

Renewable Energy World - Mon, 07/02/2018 - 19:25
As usual hot weather descended on New England in late June/early July but Vermont utility Green Mountain Power (GMP) was undaunted by peak demand. That’s because the utility turned to stored energy to reduce demand on the grid. There is a network of Tesla Powerwall batteries in Vermonters’ homes, stored solar power from GMP’s Stafford Hill Solar Facility in Rutland, and GMP’s new battery storage project in Panton. All combined that’s enough to power about 5,000 homes during the peak.

UK heatwave helps solar power to record weekly highs

Guardian - Renewable Energy - Mon, 07/02/2018 - 10:45

Hot weather saw solar briefly take over from gas as the number one energy source

Britain’s heatwave has helped break several solar power-generation records, and over the weekend the renewable energy source briefly eclipsed gas power stations as the UK’s top source of electricity.

While new solar installations have virtually flatlined over the past year, a run of largely cloudless days has seen a series of highs for power generation by the sector.

The dirty little secret behind 'clean energy' wood pellets

Guardian - Renewable Energy - Sat, 06/30/2018 - 10:00

US communities near pellet mills complain of fumes while experts say burning wood is a ‘disaster’ for climate change

It is touted as a smart way for Europe to reach its renewable energy goals. But try telling Lisa Sanchez thousands of miles away in America that burning wood chips is a form of clean energy.

The bucolic charm of her rural home in the Piney Woods forest region of east Texas is undercut by the big German Pellets manufacturing plant just beyond the bottom of her garden. The German-owned plant is capable of producing 578,000 tons of wood pellets a year, which are destined to cross the Atlantic to satisfy a vibrant market for the product there.

India's huge solar ambitions could push coal further into shade

Guardian - Renewable Energy - Sat, 06/30/2018 - 00:35

Foreshadowed 100 gigawatt tender is off the scale of country’s energy needs but represents ‘brilliant statement of intent’, analysts say

India says it intends to launch a tender for 100 gigawatts of solar power, 10 times the size of the current largest solar tender in the world – another Indian project scheduled to open for bids next month.

But analysts have said the country has neither the infrastructure nor the energy demand to warrant installing so much solar capacity in one go, saying the announcement reflects the scale of India’s ambition to become a renewable energy leader.

Intermittent approach to renewable energy | Letters

Guardian - Renewable Energy - Fri, 06/29/2018 - 15:44
We need an energy storage infrastructure, says Jim Waterton, the Swansea lagoon decision should be reviewed, argues Robert Hinton, while Dr Tim Lunel wants solar subsidies restored

Intermittency – in one word, the main problem facing many (not all) forms of renewable energy; in the UK, principally wind and solar, and now tidal (Hinkley Point C got the go-ahead despite its cost. So why not Swansea Bay? 27 June). So far, electricity from these renewable sources has been in modest amounts, and intermittency has been dealt with (I simplify, but only slightly) by backing-off gas-fired combined cycle (CCGT) plant which, together with nuclear, forms the backbone of the UK electricity generating system. When the wind is not blowing or the sun is not shining, CCGT plant is there to take the strain.

But this simple strategy fails if wind, solar, and now tidal presume to take over this backbone role. Smart metering (affecting consumers’ usage patterns) and international power exchanges can help, but the main action has to come from energy storage and regeneration plant, involving a new infrastructure to supplement hugely the existing pumped storage capability. This is bound to have serious cost implications, and until this is openly acknowledged, direct comparison of projected MWh costs from any intermittent renewable source with corresponding MWh costs from non-intermittent new nuclear generation is fundamentally invalid, and likely to be badly misleading.

Archaeologists stumble on Neolithic ritual site in Suffolk

Guardian - Renewable Energy - Thu, 06/28/2018 - 05:30

Diggers laying groundwork for a new windfarm discover previously unknown site of international significance

As diggers began to strip the daisies and buttercups and carve down through the parched clay of a field near Woodbridge in Suffolk that sloped down to a riverbank, with archaeologists watching over the pretty but apparently featureless site, something extraordinary began to emerge. Clear spring water came bubbling from the ground, and with it came massive timbers preserved so perfectly that tool marks were still visible and stake posts were sharply pointed.

The archaeologists first thought the timbers must be medieval or even Victorian, and were puzzled to find them so deeply buried. But as 30 metres of timber track were exposed, alongside other unexpected objects too, such as the massive horns and skull of an aurochs, an extinct breed of giant cattle, they realised they were dealing with something far more ancient. The timbers were 4,300 years old, according to the first carbon-14 tests, and underlying ones may be much older.
