Work From Home and Drive More Slowly To Save Energy, IEA Says

エネルギー価格が上昇しているイランの戦争の影響を受け、国際エネルギー機関(IEA)は、リモートワークや速度制限を緩和するなどの対策を政府に呼びかけています。Birol氏は、「私たちはまだエネルギー安全保障への挑戦の深刻さを十分理解していない」「1970年代のものよりも大きいし、ウクライナ侵攻後の天然ガス価格のショックより大きい」と述べています。

IEAは32カ国に加盟しており、米国、英国、オーストラリア、カナダ、日本など24か国とヨーロッパ諸国を含みます。提案された対策には以下のものがあります:
- 都市中心部へのプライベートカーのアクセス制限
- 乗車分担や効率的な運転方法の促進
- 必要な場合以外は航空旅行の回避
- ガス調理器具への切り替え

また、石油ガスの使用を特定の用途に集中させるための努力も求められています。IEA加盟国は先月、緊急備蓄の20パーセント相当である4千万バレルの原油放出に同意しました。特にアジア諸国では、イラン戦争により深刻な影響を受け、4日間の週勤務やリモートワークを義務付けるなどの緊急措置が実施されています。
As energy prices soar from the Iran conflict, the International Energy Agency is urging governments to cut energy use by taking up measures like remote work and reduced speed limits. The group warns the energy security crisis could persist for months, even if supply routes stabilize. "I believe the world has not yet well understood the depth of the energy security challenge we are facing," said IEA's executive director, Fatih Birol. "It is much bigger than what we had in the 1970s... It is also bigger than the natural gas price shock we experienced after the Russia's invasion of Ukraine." The BBC reports: Thirty-two countries are members of the IEA, including the US, the UK, Australia, Canada, Japan and 24 other European nations. Its role is to act as a global watchdog, providing analysis and recommendations on global energy problems, such as energy security and the transition to clean energy. The IEA's other suggestions for governments, businesses and individuals include: - Promoting use of public transport - Giving private cars access to city centres on alternate days - Encouraging car sharing and efficient driving habits - Avoiding air travel where possible, especially business flights - Switching to electric cooking It also said there should be a focused effort to preserve liquid petroleum gas for cooking and other essential uses, by switching bio-fuel converted vehicles onto gas and introducing other measures to reduce its use. Birol said these proposals were in addition to action taken by IEA member countries earlier this month, when they agreed to release 400 million barrels of oil, 20% of its emergency reserves. Several countries in Asia have implemented emergency four-day workweeks and work-from-home mandates as they have been hit particularly hard from the conflict. Fortune notes: "Asia is particularly dependent on oil exports from the Middle East; Japan and South Korea respectively source 90% and 70% of their oil from the region."

Hydropower Line From Quebec Could Power a Million NYC Homes

🤖 AI Summary

Quebecからの水力発電線「チャーマーリン・ヒドロニューヨーク電力輸送路」が、ニューヨーク市100万世帯を年間で供給する予定です。このプロジェクトは6億ドルで建設され、339マイルの地下線を通じてカナダのHydro-Quebecからニューヨーク市に電力を送ります。これは40年のインフラ構築経験を持つロブ・ハリソン氏が手掛ける最大のプロジェクトです。「最も目立たない大型プロジェクト」として知られています。

この巨大な計画は、カナダとニューヨーク市コウンズ沿いの埋め立て地に架かる海底線を含む複雑なルートを通じて電力を供給します。約200万フィートのケーブルがスウェーデンから輸入され、特殊な船舶が海底の掘削作業を伴う工事を行いました。

ニューヨーク市への接続には10基の新規マンホールと3マイルの地下配線が必要でした。電力はアストリアでコンバーターステーションを通じて最終的にニューヨーカーに供給されます。この施設内では、膨大な量の微細部品が搭載された巨大装置が運転されています。

このプロジェクトは複雑かつ大規模でありながら、その存在感を隠している点で独特です。
The Champlain Hudson Power Express, a $6 billion, 339-mile buried transmission line, will soon deliver Canadian hydropower from Hydro-Quebec to New York City. The project could supply up to 20% of the city's electricity and power roughly one million homes throughout the year. "This is far and away the largest project I have ever worked on," said Bob Harrison, who has worked in infrastructure for 40 years and is the head of engineering for the Champlain Hudson Power Express. "We like to say it's the largest project you'll never see." The New York Times reports: The massive power project, expected to provide energy to a million New York City customers a year, travels underground and underwater, from the northern plains at the Canadian border to the filled-in marshlands of coastal Queens, much of it loosely following the Hudson River. Its construction included the underwater installation of more than two million feet of cable imported from Sweden. It also required special boats, loaded with equipment that could shoot water jets deep into the sediment, to create trenches for the cable. Then, when it came to placing cable beneath the landscape, more than 700 land-use easements were needed, plus an additional 1.55 million feet of cable. The Champlain Hudson Power Express has found a way to plug into the city, but it wasn't easy. The work included 10 new manholes and more than three miles of new underground circuitry, according to Con Edison, the city's primary electricity provider. "It was literally a hand weave under the streets of Queens," said Jennifer Laird-White, the head of external affairs for Transmission Developers. The hydropower travels from Canada via two buried cables that are as round as cantaloupes. Those lines snake for hundreds of miles under a lake, several rivers (including the Hudson for about 90 miles) and through buried trenches alongside train tracks and roads. The cables resurface in Astoria, Queens, where a converter station shapes, filters and refines the raw power into a product that New Yorkers can consume. In two cavernous rooms that could be mistaken for "Star Wars" sets, the electricity flows through 30 hanging structures encased in what look like metallic, dinosaurlike exoskeletons. Each one weighs about as much as a small humpback whale and contains microprocessors, thousands of valves and fiber wires. "I am still wowed when I walk into that facility," said Mr. Harrison, the engineer. "I mean, it is just mind-boggling."
