Comments Off on Renewable electricity could overtake fossil fuels in Britain by next year

A new report from British power analysts EnAppSys is predicting renewable electricity will overtake fossil fuels as the main source of Great Britain’s electricity generation by next year if current trends continue. In their annual market review report for 2018, EnAppSys says that the levels of power generation from coal and gas-fired power stations fell by 6.7 percent, while generation from renewables increased 15.2 percent. If renewables do pass up fossil fuels in Great Britain in 2020, it will be a first, and it will prove that renewable energy has staying power. “It’s clear that renewables will be generating most of our power in the years ahead, with wind playing the leading role,” said Luke Clark, RenewableUK’s Head of External Affairs, told Clean Technica. During 2018, a large number of offshore wind farms were commissioned or went into full operation and the increase of wind energy led the way in renewable energy generation. Since the cost of offshore wind continues to decrease this means it will likely become the primary source of renewable  energy generation, at least in the short term.

Between the moratorium on onshore wind and the falling costs of offshore wind, that share should climb even higher. However, there are still some concerns about the UK fuel mix because of the suspension of their Capacity Mechanism— a measure designed to ensure the security of the electricity supply by paying for reliable sources. In November, the European Union ruled that the Capacity Mechanism was illegal. Those payments were going to old coal, gas , and nuclear plants, and some saw them as government subsidies. But, without that money, some of those plants may leave the market. If that happens, it will lead to “decreased security of supply.” Ultimately, the Capacity Mechanism payments will need to be reinstated or an alternative will need to be implemented to fill the gap created by the lost income.

Trump orders Perry to take steps to curb coal plant shutdowns

Comments Off on Trump orders Perry to take steps to curb coal plant shutdowns

It seems President Donald Trump doesn’t want to let coal die. Bloomberg reported he ordered Secretary of Energy Rick Perry to take steps to stem closures of nuclear and coal power plants. An emailed statement from White House spokesperson Sarah Sanders read, “Impending retirements of fuel-secure power facilities are leading to a rapid depletion of a critical part of our nation’s energy mix and impacting the resilience of our power grid .” Coal and nuclear plants are losing money as cheaper renewable energies and natural gas gain steam. Trump’s administration alleges that declines in nuclear and coal power jeopardize America’s security. According to the White House statement, the president told Perry “to prepare immediate steps to stop the loss of these resources and looks forward to his recommendations.” The Department of Energy’s strategy, as detailed in a memo Bloomberg obtained , could be to draw on power given by federal laws to create a “strategic electric generation reserve” and compel grid operators to purchase power from plants that are at risk. The National Security Council was to meet last week to talk over the idea. Related: Biggest grid operator in US attacks Perry’s proposal to prop up coal One purpose of this draft plan, Bloomberg reported, is to buy time for a two-year study probing vulnerabilities in the country’s energy delivery system. Administration officials have already used up a year of this time. Following an Energy Department grid reliability study, Perry suggested a rule that would have compensated nuclear and coal plants — and federal regulators killed the proposal. Major grid operator PJM Interconnection said in a statement its grid “is more reliable than ever” and “there is no such need for any such drastic action.” The company said it has analyzed planned deactivations of nuclear stations and found no immediate threat to reliability. PJM said, “Any federal intervention in the market to order customers to buy electricity from specific power plants would be damaging to the markets and therefore costly to consumers.” Electric Power Supply Association president John Shelk said, “National security is being invoked by people who once favored markets. Everybody loses in a fuels war.” Via Bloomberg Images via Depositphotos (1, 2)

Gorgeous barn is built of reclaimed, century-old oaks from the site itself

Comments Off on Gorgeous barn is built of reclaimed, century-old oaks from the site itself

In 2017, Dutch design firm HilberinkBosch Architects found out that seven of their century-old oak trees were in ailing health and would need to be cut down. Instead of sending the oaks to the paper mill, the architects decided to try their hand at building a timber barn using traditional construction techniques. The result—called the Sixteen-Oak Barn—was a stunning success that combines modern and rustic features with large panels of glazing and untreated timbers. The idea for a barn came from the local building vernacular in the Dutch region of Meierij van ‘s-Hertogenbosch, which features gabled farmhouses traditionally built from locally available materials . In a design the architects describe as “haphazard aesthetics,” the Sixteen-Oak Barn was constructed of the locally felled, century-old oak trees in addition to a couple of oaks sourced from the nearby Wamberg estate. The barn comprises a carport, storage room, and a workshop / meeting room for office use. There is also an addition loft space located above the storage room. A mobile sawmill brought on-site was used to cut the core sections of the felled oak tree trunks into structural timber for the frames, roof, and siding. The transverse-frame barn involves tie rod trusses and roof rafters to hold up an asymmetrical shingled roof clad in cleaved soft sapwood. Stanchions with bark serve as solar fins to shield the glazed facade from unwanted solar heat gain. Board-formed concrete complements the timber palette indoors. Leftover timber was chopped and stored as firewood in the barn’s recessed north facade.

Untreated timber, concrete and glass have been intermingled in various ways. The irregular dimensions of the wood used to build the formwork resulted in far from perfect concrete surfaces.” + HilberinkBosch architects Images by René de Wit
