Zendure SuperBase V vs EcoFlow DELTA Pro: buy the DELTA Pro (3,600Wh, about $1,799). The SuperBase V has more solar input but no current US listing.

Floating solar explained: water cooling adds about 3-6% output, but NREL puts the cost 25% above ground-mount. Where it pays, and the biggest projects.

Does rooftop solar pay off in 2026? Without the 30% credit, an $18,000 6kW system pays back in about 15 years at $0.16/kWh, 13 at $0.18. Payback by state.

Agrivoltaics produced 60-86% more output per acre in Fraunhofer's trials. How dual-use solar farming works, which crops do well and US growth (10+ GW).

US offshore wind in 2026: Vineyard Wind is built and four more farms are finishing, while new leasing is frozen and leases are being bought back.

Demand response pays you to cut load at grid peaks. How it works, what utilities pay (SCE $75 to join, Mass Save $275/kW for batteries) and Texas in 2023.

About 34 million households reported energy insecurity in EIA's last survey. How LIHEAP, weatherization, community solar and fading solar credits fit in 2026.

The future of home energy by 2030: heat pumps, bidirectional EV charging, smart panels like Span, and how electrification can double a home's power use.

Community solar explained: how it works, where it's available, real savings (5–55%), and what to watch for in contracts. No roof, no installation required.

Off-grid power for an average US home runs roughly $80,000-$150,000 by our estimate, with no federal credit in 2026. Why grid-tied plus battery usually wins.

Solar panels cost a median $3.60 per watt installed ($3.00 for cash buyers), Berkeley Lab says: $18,000-$21,600 for 6kW. No federal credit for 2026 installs.

2026 electricity cost by state: Hawaii $0.463/kWh, North Dakota $0.124, US average $0.182 (EIA, Jan-Jul). Full 50-state table and why rates vary.

Onshore vs offshore wind energy: cost comparison, capacity factors, siting challenges, and when each technology makes sense for the grid.

How grid-scale battery storage works, which chemistries utilities use, what the 2025 Moss Landing fire means for safety, and why storage duration matters.

Vertical-axis wind turbines take wind from any direction but capture less energy than standard turbines. Are they useful on urban rooftops or hype?

The duck curve explained: why midday solar oversupply and steep evening ramps strain California's grid, and how TOU rates and batteries respond.

Are home wind turbines worth it in 2026? Small wind cost about $7,370 per kW installed (PNNL), and only windy, open sites pay back. When solar beats wind.

Biomass energy made about 47 billion kWh of US power in 2023. When it helps (mill waste, biogas), when it hurts (whole-tree pellets) and pellet stoves.
