Warming U.S. Cities Face Higher Cooling Demand and Energy Bills
Analysis of cooling degree days (CDD) shows that 97% of 241 major U.S. cities experienced increased cooling demand since 1970, with an average increase of 37%. This trend, combined with a 31% rise in residential electricity prices between 2020 and 2025, increases the financial burden on households, particularly low-income families. In 2020, the ten states with the highest cooling costs saw average household expenditures between $378 in Hawaii and $712 in Arizona. Future projections suggest U.S. household cooling demand will rise 43% by 2050. The report also highlights systemic risks, including electricity grid strain, increased carbon emissions from fossil-fuel-reliant cooling, and the urban heat island effect caused by waste heat from air conditioners.

Powering Canada Forward Fund
The Canadian Climate Institute proposes a Powering Canada Forward Fund (PCFF) to address the financial challenge of scaling Canada's electricity grid. Because current regulatory models pass the cost of new infrastructure immediately to ratepayers, there is a risk that rising bills will deter the electrification needed for climate goals. The PCFF would use federal funding to cover the gap between utility costs and customer receipts, deferring the cost of anticipatory build-out until new demand arrives to share the burden. This mechanism shifts demand risk from ratepayers to the federal government and ensures that the benefits of a larger, more efficient system are shared across generations of users.

Let the Sun In: Clean Energy is the Cheapest Way to Meet Rising Demand
A national analysis comparing two futures for U.S. electricity demand growth through 2030 finds that a clean energy approach is significantly cheaper than a fossil fuel-heavy one. Relying on fossil fuels would add $29.7 billion annually to customer bills by 2030, whereas a clean energy scenario would reduce overall costs by $5.1 billion annually compared to the high fossil scenario. Furthermore, clean energy provides a hedge against price shocks; in a scenario similar to the 2022 price spike, clean energy would yield total savings of $13.5 billion per year compared to fossil fuel reliance.

How the Philippines ' rooftop solar surge can flip the energy emergency script
Rooftop solar capacity in the Philippines has likely doubled between April 2025 and April 2026, reaching approximately 1,300 MW. This growth is driven by surging electricity prices, which have reduced payback periods for residential, commercial, and industrial users to between 2.3 and 3.1 years. The report highlights a massive influx of solar panel imports from China and the emergence of domestic manufacturing. To further scale rooftop solar to a target of 3,500 MW with 4,500 MWh of battery storage within 24 months, the author recommends expanding low-interest loan schemes, legalising 'plug-and-play' solar kits under 800 watts, and implementing a distributed grid-battery project.

A Smarter Way to Pay: Public Financing for Affordable Transmission Development in New England
The report argues that New England's transmission costs are the highest in the U.S., driven by a lack of cohesive planning and a reliance on expensive private capital. It proposes replacing private equity and debt with low-cost, tax-exempt public financing, which could save ratepayers up to $8.3 billion on new transmission and $1.1 billion on asset condition projects. The authors suggest several implementation pathways, including integrating public financing into ISO New England's Longer-Term Transmission Planning (LTTP) process or creating new state transmission authorities.

Latest energy shock reminds Europe of its risky gas reliance
A conflict in the Middle East involving Israel, the US, and Iran has caused global fossil fuel supply disruptions, leading to a nearly 50% increase in European gas prices in early March 2026. The briefing highlights that the EU's fossil import bill rose by an estimated €2.5 billion in the first ten days of the crisis. It argues that countries with high gas reliance for electricity, such as Italy, are most exposed to price spikes, while those that have decoupled gas from electricity prices, like Spain, are more resilient. The author contends that electricity market reforms or removing carbon costs (EU-ETS) are less effective than investing in renewables and clean flexibility to ensure long-term energy security.

Renewables cut annual electricity bills by one month in Türkiye
In 2025, renewable energy reduced annual household electricity bills in Türkiye by an average of 9%, with some monthly savings reaching 17%. While renewables lowered wholesale prices by up to 45%, the full benefit is not passed to consumers due to regulated tariff structures and the lack of hourly demand-side management for residential users. The report suggests that implementing demand-side management could double annual household savings to 15.7%, and removing the zero-price floor to allow negative pricing would further lower costs.
