    Shetland Backs Plan to Connect Islands with £1.5bn Undersea Tunnels

    Shetland Backs Plan to Connect Islands with £1.5bn Undersea Tunnels

    Councillors have backed initial plans to connect some of Shetland's islands with undersea tunnels, which could be in place within eight years. A feasibility study proposed replacing ageing ferries with tunnels from Shetland's mainland to Yell and from Yell to Unst, describing them as "economically transformative". Two more tunnels, to the islands of Whalsay and Bressay, could follow under the plans - which it is estimated could cost £1.5bn. Council leaders say the tunnels would be cheaper than building new ferries and replacing harbours. At a meeting in Lerwick on Tuesday, councillors approved exploring funding options. Council chief executive Maggie Sandison said the project was not going to be easy, but she thought pursuing a funding solution was the "right thing to do". This could come from a mixture of private investment, public subsidy and borrowing, alongside tolls to cover maintenance costs. The council's transport chairperson, Moraig Lyall, said the report showed there were no technical barriers to building tunnels, which would be "cheaper in the long run" than ferries. Costs have risen sharply in the past decade, with some routes struggling to meet demand for vehicle places. Lyall said: "The system we have that has served us well for decades is now no longer able to do that. It doesn't have the capacity and we're struggling with other things, like the ability to crew the system adequately. These barriers to giving the islands a really good service are not going to be easily overcome by replacing ferries with other ferries. The tunnel is the answer that we believe will help us solve these problems."

    This Island in the Great Lakes Wants to Tap Waves for Energy

    This Island in the Great Lakes Wants to Tap Waves for Energy

    Hydrokinetic energy from the waves surrounding Beaver Island could improve electricity reliability and push an emerging technology forward. Beaver Island sits in the middle of the northernmost end of Lake Michigan, about 70 miles from the maritime border with Canada. The forested island, just a little bigger than San Francisco in size, is a popular summer destination for tourists and home to about 600 permanent residents. Getting there requires a boat or plane ride. Getting electricity to the island isn't as easy. Power comes from mainland Michigan through cables that cross roughly 30 miles of lake bed. Outages are common during extreme weather, or when there are problems with the sensitive wires. The devastating ice storm that walloped the state last year knocked out power to the island for weeks. That's got some residents hoping to see a more reliable source of power that's generated where they live. Turns out, there's an abundant source nearby: the waves that surround the island. Earlier this month, researchers from the University of Michigan gathered on the shoreline to deploy two devices that convert the kinetic energy of waves into electricity. The gadgets — prototypes that look like small boats framed with PVC pipes and are about the size of a yoga ball — demonstrated their potential by powering a light bulb and charging a cell phone. The project is one of many efforts across the country to use alternative sources of energy to improve reliability in remote places. In this case, the researchers spent two years gathering input from residents, who said providing a dependable source power to the airport was a priority. "We need to work with the community together to identify the need and design together with them," said Lei Zuo, an engineering professor at the University of Michigan and the lead researcher on the project. Several residents already power their homes and businesses with solar panels or geothermal energy, and the island has previously received federal funds to improve access to renewables. Similar programs and grid modernization plans face an uncertain future as the Trump administration cancels grants and programs, raising questions about how such projects will be funded in the years ahead.

    Island Solar Project Will Help Tackle Fuel Poverty

    A North Ayrshire Council partnership project has seen more than 30 homes on Great Cumbrae being fitted with solar panels and battery storage systems. The Millport Solar PV and Battery Project is a community-led, phased programme with three aims: reducing Scope 2 carbon emissions - resulting from grid-supplied electricity; tackling fuel poverty and; building local energy resilience. It is part of the Carbon Neutral Islands (CNI) Project, which is a Scottish Government programme for government commitment, supporting six islands with the aim to demonstrate the climate-resilience and low carbon potential of islands. The latest phase alone is expected to mitigate approximately 24 tonnes of CO2 emissions in its first year, contributing to the island's decarbonisation goals as well as financial savings of over £20,000. This has been a highly successful partnership, managed by the Council's Energy and Sustainability team, locally led by Carbon Neutral Cumbrae and supported by Scottish Government Island's Programme funding. Installation works have been carried out by energy services company Union Technical, who completed 31 installations during the latest phase. Councillor Eleanor Collier visited Millport on 27 May to celebrate the progression of energy resilience on the island and see first-hand the impact of the latest phase of the island's flagship energy retrofit programme.

    Prince Edward Island Looks to Turn Animal Waste Into Energy for Homes

    Prince Edward Island Looks to Turn Animal Waste Into Energy for Homes

    If you asked someone what dead cattle and lobsters have in common, they probably wouldn't guess that they could be used to power homes on Prince Edward Island. But, here we are. P.E.I. Agriculture Minister Bloyce Thompson said in the legislature Friday that it's a promising idea that's likely to happen as government explores creating a biodigester system in the province. "We are looking at a model of a biodigester that will digest animal waste, seafood waste and other food waste that possibly could power Borden-Carleton, we'll say," Thompson said during question period, referencing the town of just under 800 residents at the foot of the Confederation Bridge.

    Stewart Island Solar Farm Could Be Running by Christmas

    Excerpt from whatsoninvers.nz Stewart Island could have its long-awaited solar farm operational by Christmas, with construction potentially starting as early as June, officials say. The island's 480 residents currently rely entirely on diesel for electricity and are facing steep price increases due to Middle East conflicts driving up fuel costs. Southland Mayor Rob Scott said the council is exploring ways to fast-track the $15 million government-funded project by classifying it as emergency works under the Resource Management Act.

    Keeping the Lights On: How Cuba Is Fighting an Energy Crisis Under Tightened Sanctions

    Excerpt from powermag.com The current state of the national power grid in Cuba is a response to an exceptionally complex scenario, marked by the intensification of the U.S. embargo and its direct impact on fuel supplies. This was the message delivered by First Deputy Minister of Energy and Mines, Argelio Jesús Abad Vigoa, during his appearance on the Cuban TV program “Mesa Redonda.” The official distinguished two clearly defined phases. Until the end of last year, although the embargo remained rigorous and had imposed severe restrictions for more than six decades—including the persecution of suppliers, sanctions on shipping companies, and financial obstacles—Cuba managed to acquire fuel on the international market.

    Sri Lanka declares Wednesdays off as Asian countries try to conserve fuel

    Excerpt from bbc.com Sri Lanka has declared every Wednesday a holiday for public institutions to conserve fuel as the island nation grapples with possible shortages in the wake of the US and Israel's war with Iran. "We must prepare for the worst, but hope for the best," President Anura Kumara Dissanayake said at an emergency meeting with senior officials on Monday. This is the latest in a series of belt-tightening measures undertaken by Asian countries since the war choked off the Strait of Hormuz, which used to carry millions of barrels of oil from the Gulf into the region. Nearly 90% of all the oil and gas flowing through the strait last year was bound for Asia, which is the world's largest oil-importing region.

    CalMac ferries could have lower capacity with rise of EVs

    Excerpt from heraldscotland.com The rise of electric vehicles could result in Scotland's ferries having a lower vehicle capacity, CalMac has warned. Due to the presence of large battery packs, modern electric cars are on average 200-400kg heavier than a petrol equivalent. At a meeting in the Western Isles, the ferry operator was asked whether this would mean that vehicle capacity could be reduced on sailings as more EVs enter the market. In comments reported by The Scotsman, Outer Hebrides area manager David Hamill said: "Yes, I think it’s fair to say potentially it could.

    From Hormuz to the Canary Islands: the price of a distant war

    From Hormuz to the Canary Islands: the price of a distant war

    Excerpt from canarias7.es Wars in the Middle East are rarely explained solely by the clamor of headlines. For decades, this region has been the epicenter of the most sensitive points in the global energy system, and each military escalation casts a shadow that reaches far beyond its borders. The current tension—with Iran, Lebanon, and the Strait of Hormuz at the eye of the storm—once again forces us to confront our own fragility: the stability of the global economy remains chained to a handful of maritime corridors. This is certainly not the first time we've stumbled over this stone. Back in 1991, the Gulf War confirmed that control of crude oil and its transport routes is the true driving force behind high-level international politics. That intervention was sold to us as a crusade for legality after the invasion of Kuwait, but this appeal to law was, to a large extent, pure window dressing. As so often happens, the rules of the international game were invoked while they served the interests of the major powers and discarded when they ceased to be useful. Beyond the rhetoric, the conflict laid bare a stark reality: the Persian Gulf was—and still is—a key piece of the economic chessboard.
