Iran war sparks renewables boom as Europeans rush to buy solar, heat pumps, EVs

US and Global Renewables Trends

  • Some argue the US is already rapidly shifting: in 2026 planned new generation capacity is mostly solar (51%), storage (28%), and wind (14%), with only 7% natural gas.
  • Others say the US is moving “backwards” at the federal level but forward at state/local and household levels, with people reacting to energy insecurity.
  • China is cited as proof deployment can go much faster (~400 GW renewables annually), suggesting US pace is constrained by policy, not physics.

Permitting and Regulation

  • One commenter describes rooftop solar permitting as vastly harder than simply connecting to the grid or even building an oil derrick, blaming local planning/zoning and industry influence.
  • Another points to a DOE-backed tool to automate residential solar permitting and notes some states pre-empt local opposition for utility-scale projects.
  • Overall sense: regulation is seen as inconsistent and often dysfunctional.

Oil Prices and Political Catalysts

  • Geopolitical shocks and high fuel prices are framed as powerful drivers of efficiency and green tech, similar to the 1970s.
  • There’s a claim that a US administration hostile to climate policy could ironically accelerate EV uptake if gasoline spikes to $5–6/gal.
  • Others caution this impact depends heavily on how long prices stay high.

EV Capabilities, Adoption, and Policy Barriers

  • One side: EVs are “mostly solved” for the mass market; ~25% of global car sales are electric (including plug‑ins), over 50% in China, ~100% in Norway, and internal-combustion sales have already peaked.
  • Another side: today’s EVs still fail as full ICE replacements for some users—either insufficient range / slow charging, or acceptable performance at too high a price.
  • A specific wish list: ~700 km range or 5‑minute 20–80% charge at ~€35k.
  • EU tariffs on Chinese EVs are blamed for slowing access to cheaper, better-performing models.
  • There is debate over lumping plug‑in hybrids with battery EVs in adoption stats.

Driving Patterns and Charging Experience

  • One user insists on very long-range capability for frequent ~1,100 km trips; others call that usage atypical and question the tradeoff.
  • EV owners report real-world trips involve short (10–20 minute) fast charges every 2–3 hours, usually from 10–80% state-of-charge, not 0–100%.
  • They emphasize that daily charging happens at home, so “waiting for a charge” is mostly a road-trip issue.

Alternative Fuels and Engine Limits

  • With high diesel prices in Europe, vegetable oil as fuel is mentioned.
  • Another poster notes this can damage modern direct-injection/common-rail diesels, and is only suitable for older indirect-injection engines.

Overall Attitudes

  • The thread mixes optimism (technology and economics are aligning for a rapid transition) with skepticism (policy, regulation, cost, and specific user needs remain serious obstacles).
