For more on the data and our methodology download the data dictionary and data library: Large-scale clean energy generation and battery storage projects can help deliver more affordable energy to people across the United States. As with all large infrastructure development, communities that host these projects may have concerns about what benefits the projects will deliver to their community, and the project’s potential impacts.

Across many fields, scientific and technological progress is characterized by periods of steady improvement punctuated by breakthroughs that enable rapid advances. Communications, lighting, water treatment, and many other sectors have followed this pattern. Over the past decade, carbon dioxide removal (CDR) has likewise seen significant progress across a growing range of approaches.

India’s summers are testing the limits of what its people and power grid can absorb. And with each passing summer, more homes are turning to air conditioners (ACs) for respite as the need for cooling grows. Domestic AC production from about 6 million units in 2021, is expected to nearly quadruple and reach 24 million units by 2030. The challenge is increasingly becoming how to deliver comfort to people without locking in avoidable energy use and stretching power grids to their limit.

Batteries, semiconductors, motors, and the energy systems that power them underpin the modern economy — from consumer electronics and vehicles to the electric grid and defense systems. The minerals that enable these technologies are therefore increasingly viewed through an economic and national security lens, particularly as refining and processing remain highly concentrated geographically.

Article September 30, 2026 Building more resilient critical mineral supply chains requires strategies tailored to the economics of each market By Sudeshna Mohanty and Kriti Singh Batteries, semiconductors, motors, and the energy systems that power them underpin the modern economy — from consumer electronics and vehicles to the electric grid and defense systems.

Article September 29, 2026 Across standards, buyer due diligence, and data systems, social integrity is becoming a more visible part of carbon credit quality. By Apoorva Sahay and Caitlin Smith A carbon credit represents one metric ton of carbon dioxide equivalent (tCO2e) avoided, reduced, or removed through a project or program that operates among people, communities, institutions, and cultural contexts.

Article September 28, 2026 Nearly every Bay Area home saves by upgrading to a heat pump water heater, with the most consistent savings going to households with the least room in their budgets By Meron Lemmi, Jonny Kocher, Jed Holtzman, and Ryan Shea Rent, mortgage, groceries, utilities…the squeeze is real, and San Francisco Bay Area families feel it every month.

Imagine if your annual income tax liability was based on your single largest paycheck instead of your total income. Those who earn commissions or employees who earn annual bonuses would owe far more than someone with the same annual income but who earned it from a steady weekly paycheck. And we would logically expect companies and employees to seek out compensation structures as a reaction to this illogical tax structure.

RMI analyzed the annual energy bill impacts of replacing delivered fuel space heating systems with heat pumps across Maryland’s electric utility service territories. This focused on the approximately 330,000 Maryland single-family households that use delivered fuels to heat their homes (14% fuel oil and 4% propane across all Maryland single-family homes). Why heat pumps?
