I'm writing a book on Brazil's energy development, examining the nexus of prices, profits and politics. Everyone's views and suggestions are welcome.

What about a Green Bay model? 600,000 buying one share each for $100?

Most of us can’t afford electrification just yet, and even when we can the plug in takes over 50% fossil. For example, in Maryland USA, nearly 75% is gas fired. Political action has to focus on the supply side, the expected ROI, to accelerate the transition.

Bryan, if we focus on consumers we lose track of the real decision makers: investors. The focus has to be on investors and expected ROI, that is the real tipping point between clean and fossil energy projects.

Minnesota: the use of violence by federal agents is reminiscent of El Salvadoran armed forces in the 1970s & 1980s. The indiscriminate use of violence to intimidate and coerce civilians, creating the political and socioeconomic conditions that led to an exodus to the USA: ironic.

Dear Norm, I’m from Seattle and big fan of your work with Mariners. Loved your walk to the mound, electric. Noticed your shoutout to Corinthians no Brasil πŸ‡§πŸ‡· , wondering what kind of work you do now and whether you are connected to Brazil in any way?

What’s the best balcony solar package on the market: quality and price?

Yep, in an era of electrification, unbundling and marketization raises costs and profits. Can US industry afford this? Maybe, but it reinforces the political pressure for protection, shifting costs onto consumers across the board.

Even if U.S. gas remains below global price it will bake in infrastructure, locking U.S. industry to expensive energy systems, raising costs, limiting export competitiveness, and signaling strategic misdirection.

Picking up Bill. Most of my associates in oil and gas ⛽️ talk addition while standard scholarship says transition. Agreeing with Bill, we are moving through a transformation that currently looks like addition but the real game changer is increasing energy self- reliance. More later.

I don’t see an EO posted yet, but in the end it’s CBP’s ball.

Certainly not what democracy looks like. If the Congressional Republican leadership allows this, well it’s a downward spiral. All eyes πŸ‘€ on Speaker Johnson. Wait, Johnson has allowed it without protest.

Bukele’s father Armando was brilliant in politics and business, Nayib majored in marketing and has not stopped since, all smoke, mirrors and torture.

Fascinating
1. Admin may not have informed Congress but has been talking regime change w US oil industry
2. Oil at $60, US firms not excited about major capex to get VZ heavy sour crude
3. Sounds like WH wants to prod oil firms to make their vision happen, more than WH doing US oil's bidding

#Venezuela the talk of the town but I am also thinking about the USA capture of Manuel Noriega of Panama in 1989, and destruction of the Defense Forces. The comparison is limited but both framed as anti-narcoterrorism actions. Washington famous for creative pretexts.

Colegas, estou buscando estudos que tratam a transiΓ§Γ£o energΓ©tica ao nΓ­vel de anΓ‘lise municipal no Brasil.

Isso pode incluir variΓ‘veis ​​como instalaΓ§Γ΅es de #energiaeΓ³lica, projetos de #energiasolar, projetos de #biocombustΓ­veis ou biomassa, estaΓ§Γ΅es de recarga para veΓ­culos elΓ©tricos, etc.

New to Blue Sky and interested in learning more about energy, policy and politics, technology and behavioral dimensions of the #energytransition in #Brazil and worldwide.
