The report argues that current US energy efficiency programs are overly complex, resulting in low participation rates (0.5% to 3% of households) and significant barriers for low-to-moderate income (LMI) families. To drive heat pump adoption and meet climate targets, the document recommends simplifying incentive structures (e.g., using $/unit instead of $/BTUh), aligning equipment specifications with federal standards like ENERGY STAR, and providing up-front discounts with prompt contractor reimbursement. It emphasizes the need for long-term funding (3-5 years), market development through workforce training, and a 'climate-forward' framework that prioritizes greenhouse gas reductions over simple energy savings. For equity, it suggests partnering with community-based organizations, setting LMI-specific budget targets, and funding pre-electrification measures like electrical panel upgrades.

In 2024, wind and solar combined to generate 17% of US electricity, surpassing coal (15%) for the first time. While solar generation grew by a record 27% and battery storage expanded rapidly, overall power sector CO2 emissions rose slightly by 0.7% because a 3% increase in electricity demand drove higher gas generation. Despite this, carbon intensity reached a record low of 384 gCO2/kWh.

The report finds that the Clean Power 2030 Action Plan will reduce gas imports for power generation by 57% by 2030, but notes that the UK remains vulnerable to price shocks due to continued import reliance in heating, transport, and biomass power. It argues that transitioning to heat pumps and electric vehicles would significantly lower import dependence and household costs, as a 2030 heat pump is forecast to be 85% less reliant on imports than a gas boiler.

An analysis of Southern California's heating equipment shows that heat pumps can be cheaper than gas alternatives due to incentives, potentially saving low-income households over $10,000 with federal rebates. However, fragmented application processes and insufficient funding levels hinder widespread adoption.

The document identifies five critical areas for improving the success rate of first-of-a-kind (FOAK) industrial heat decarbonization projects: customer relationship management, site evaluation, project scoping, expertise/oversight, and contract drafting. It argues that these projects are prone to a 'snowball effect' of pitfalls—such as inaccurate site evaluations and unclear scopes—that can lead to project cancellation. By implementing strategic partnerships, detailed early-stage engineering, and flexible contracting, the document suggests that FOAK projects can move from 'project to product,' potentially unlocking a 2%–5% overall emissions reduction in the United States.

The author contends that customer-driven demand-side management—such as smart thermostats, heat pumps, and optimized EV charging—can serve as a 'virtual power plant' to maintain grid stability. The text highlights a successful Ontario program that created a 90-megawatt virtual power plant and calls for federal and provincial policy shifts to prioritize energy efficiency investments over fossil fuel infrastructure.

The document proposes a shift from traditional technology-replacement efficiency to a 'whole-systems' approach. It argues that combining electrification with energy end-use efficiency (reducing the demand for energy services) can reduce overall energy demand by 50-75%. The author provides sector-specific examples: in buildings, through passive design and compact urban development; in mobility, via land-use reforms and smaller, lighter electric vehicles; in freight, through modal shifts to rail and material demand reduction; and in steel, via circularity and material substitution. The brief concludes that achieving the COP28 goal of doubling energy efficiency improvement rates requires engaging a diverse range of stakeholders to trigger social tipping points.

The report assesses Japan's second NDC, which targets a 60% reduction in greenhouse gas (GHG) emissions by 2035 and 73% by 2040 compared to 2013 levels. The authors argue these targets are insufficient compared to the global average required to limit warming to 1.5°C and risk Japan losing market share in the global clean energy transition. Key recommendations include accelerating the deployment of solar and wind power, implementing a more effective carbon pricing mechanism with a binding cap, and establishing a clear roadmap for the phase-out of coal-fired power plants.

Analysis by Climate Central shows that all 50 U.S. states and 99% of 242 analyzed major cities have warmed since 1970. Alaska was the fastest-warming state, while Reno, Nevada, experienced the highest city-level temperature increase. The document links these trends to rising greenhouse gas concentrations, which reached 427 ppm of CO2 in 2025, and advocates for the transition to zero-emission vehicles, solar and wind power, and heat pumps to mitigate future risks.

A survey of 915 registered U.S. voters in May 2025 reveals broad support for clean energy research, soil restoration, and the Paris Climate Agreement, though significant political polarization remains regarding the economic impact of the energy transition and the priority level of global warming. While many voters express willingness to take political action if asked, actual engagement remains low, hindered by barriers such as a lack of solicitation and perceived inefficacy.

The document examines how current electricity rate designs in the U.S. often overcharge heat pump users because their peak demand occurs in winter, while grid peaks typically occur in summer. Using data from NIPSCO in Northern Indiana, the brief demonstrates that aligning rates with the actual cost of service could save electrified customers hundreds of dollars annually. It proposes several rate reform options—including seasonal heating rates, time-varying rates, and separate customer classes—while emphasizing the need for affordability measures for low-income households and the long-term evolution of rates as the grid transitions to clean energy.

Ember argues that the EU must accelerate the deployment of wind, solar, and clean flexibility solutions to achieve energy self-sufficiency and security. The response emphasizes the need for a "Smart Electrification" Action Plan, the complete cessation of Russian fossil fuel imports by 2027, and the modernization of grid infrastructure and cross-border interconnections, particularly in Central and Eastern Europe.

The re-election of Donald Trump may slow US clean technology deployment through the potential repeal of Inflation Reduction Act (IRA) funds and EV tax credits, potentially shifting leadership to emerging economies. The global market for six key technologies—solar PV, wind turbines, EVs, batteries, electrolysers, and heat pumps—is projected to exceed USD 2 trillion by 2035, with global trade reaching USD 575 billion. China currently leads with 70% of the market for these technologies, though it faces risks from proposed US tariffs of 60% on all imports and 100% on EVs. Other nations may benefit: India could become a net exporter of clean technologies by 2035 with annual exports of USD 30 billion, and Brazil is well-positioned in wind turbine blade production, currently accounting for 5% of the global market. In the Global South, renewable energy potential is 400 times greater than fossil fuel production, and solar is expected to have lower upfront costs than coal in Vietnam from 2024 and in India from approximately 2027.

The briefing outlines a three-part agenda for the next US administration to maintain the momentum of its green industrial strategy. It emphasizes the need to bridge the gap between initial investment and long-term economic stability by streamlining permitting, diversifying supply chains to reduce reliance on China, and ensuring that clean energy benefits reach low-income and legacy industrial communities. The author advocates for a 'private-sector-led, government-enabled' framework supported by strategic governance mechanisms to ensure the US remains a global leader in cleantech innovation and manufacturing.

The report argues that 'clean flexibility' acts as the 'brain' of a clean power system, balancing supply and demand in real time to ensure electricity is clean every hour. It categorizes nine flexibility tools into four functional areas: Store (pumped hydro, batteries, long-duration energy storage, and green hydrogen), Shift (peak shaving and smart electrification), Share (grids and interconnectors), and Supply (improving fossil plant flexibility and smarter wind/solar operation). The document emphasizes that while some tools are basic and cheap, others are more complex and costly, and the optimal mix depends on the specific power system. It concludes by urging COP29 to expand its focus beyond storage, grids, and hydrogen to include the full portfolio of flexibility solutions.

Thermal batteries can abate up to 99% of heat emissions in US chemical and refining plants by storing renewable electricity as heat in materials like graphite or bricks. These systems can provide heat up to 1800°C for reactions and distillation, with a levelized cost of heat between $20 and $87 per MWh. Integration involves assessing heating needs, retrofitting steam systems, and implementing automated charging based on electricity prices. While heat pumps are suitable for processes up to 200°C, thermal batteries address higher temperature needs. The guide advocates for policy reforms, including wholesale electricity rate access and permitting reform for non-adjacent parcels, to enhance the viability of industrial electrification.

The report argues that clean electrification is essential for UK energy security, as the transition to electric vehicles and heat pumps significantly reduces overall energy demand and fossil fuel imports. It highlights that the UK's power sector has become more efficient as wind and solar displace coal and gas, and that electrification currently reduces fossil fuel demand four times more than the additional electricity demand it creates.

Clean energy investment in the U.S. more than tripled between 2018 and 2023, reaching nearly $248 billion annually. Investment is concentrated in the South and West, with zero-emission vehicles, solar power, and wind power serving as the primary drivers of growth across different regions and states.

The UK officially entered a coal-free power era on 1 October 2024 with the closure of the Ratcliffe-on-Soar plant. This transition saw power sector emissions drop by 74% between 2012 and 2023, driven by a combination of carbon pricing, renewable energy growth, and grid investment. The report argues that while the coal phase-out provides a roadmap, the next goal of clean power by 2030 will require a more complex whole-systems approach to displace gas and manage grid stability.

Ember proposes four key actions for the EU Energy Commissioner: a "Smart Electrification" Action Plan to shift subsidies toward clean technologies, a "Future Grids" Task Force to implement existing grid policies, a joint DG ENER-DG AGRI strategy for agri-PV to align energy and agricultural policies, and a transition to open energy data and system models to improve transparency and investment decisions.
