The Orphan Well Case For Renewable Energy
Oklahoma has made progress in utilizing wind energy resources, ranking #3 in total renewable energy production and #4 in net power generation from renewables. Despite challenges with pollution and abandoned wells from the oil and gas industry, the state is a renewable energy leader with potential for solar energy growth. Renewable energy opportunities are emerging, with farmers and property owners pursuing solar panels and wind turbines for new revenue. The Energy Department is exploring harvesting geothermal energy from oil and gas wells, as well as repurposing unused oil storage tanks for energy storage, showing that Oklahoma has the potential to grow its renewable energy profile alongside its fossil fuel industry.

Assessing Global Progress 10 Years After Paris Climate Accords
Despite criticism, the Paris Climate Accords have led to significant progress in the shift towards clean energy, with renewable energy growing by 15% and accounting for over 90% of new power generation capacity. Investment in clean energy has surpassed that in fossil fuels, and electric vehicles now make up a fifth of new car sales globally. The agreement has reshaped policy, finance, and sectoral rules, but its ultimate success depends on political leaders closing the ambition gap, phasing out fossil fuels, and scaling up finance for a just transition. Commitments made since the Paris agreement have brought the projected temperature increase down to about 2.8°C, but more ambitious action is needed to phase out fossil fuels and meet net zero emissions targets earlier.

Environmental News Network – New Window Insulation Blocks Heat, but Not Your View
Physicists at CU Boulder have created a groundbreaking material called MOCHI that can be applied to windows to improve energy efficiency in buildings globally. This transparent and long-lasting insulator does not obstruct the view through the window, unlike traditional materials. MOCHI addresses the need for transparent insulators to block heat exchange, offering a promising solution for reducing energy consumption and greenhouse gas emissions in buildings. Climate solutions experts should take note of this innovative technology as a potential tool for combating climate change.

Our Power News – What was different about this year’s UN climate talks?
World leaders marked the 10th anniversary of the Paris Agreement at COP30 in Belém, Brazil, with historic progress towards limiting global warming to 1.5°C and transitioning away from fossil fuels. Indigenous delegations played a crucial role in advocating for climate action, securing the demarcation of territories and pushing for community-led renewable energy. The momentum towards forest protection, accountability for polluters, and clean energy as a right is growing, with renewable energy on track to meet all new electricity needs by 2025. Continued support is needed to demand real climate action and build a powerful climate movement for a safe and better future.

Batteries now cheap enough to make dispatchable solar economically feasible
Utility-scale battery costs have fallen to $65/MWh outside China and the United States, making solar power more reliable. Ember reports a significant drop in battery costs in 2024 and further declines in 2025, making storage more accessible for dispatchable solar projects. The cost of a full utility-scale battery system is $125/kWh for long-duration projects of four hours or more. The levelized cost of storage (LCOS) is calculated at $65/MWh, factoring in various costs and improvements in efficiency and financing. Solar power is now considered anytime dispatchable electricity, changing the game for countries with high solar resources and growing energy demand.

Cambridge startup targets 15% module efficiency gain
Cambridge Photon Technology, a UK-based startup, has secured funding to commercialize a photon multiplication technology that can boost solar panel output by up to 15% without changing existing manufacturing processes. The technology splits high energy photons into two half-energy infra-red photons, increasing the number of usable photons for silicon PV cells. In addition to efficiency gains, the technology also reduces heat and acts as an ultraviolet photoprotective agent, contributing to the preservation of a PV module's intrinsic efficiency over time. The startup plans to demonstrate the technology's effectiveness to the industry over the next two years and investigate its impact on module temperature and UV degradation, with the potential to significantly improve the performance of photovoltaic modules.
