The rise of home batteries, often bundled in virtual power plants (VPPs), is enabling households to store solar energy and feed it back to the grid during peak demand, reducing strain on traditional power infrastructure. This decentralized approach is reshaping how electricity is distributed and managed, offering a cleaner and more resilient alternative to fossil-fuel peaker plants.

Spain's solar electricity prices have fallen so low due to oversupply that investors are struggling to profit, leading some to seek exits from the market. The glut has pushed daytime power prices near zero, undermining the business case for new solar projects despite the country's strong renewable energy growth.

This 2008 article explains the difference between AC (alternating current) and DC (direct current) solar panels, focusing on how solar cells produce DC electricity and the need for inverters to convert it to AC for home use, while also discussing the pros and cons of each system type.

Spain's rapid expansion of solar and wind energy has led to an oversupply that is crashing power prices, making renewable energy projects unprofitable and driving investors to seek ways to exit their positions.

Panasonic has launched a new CO₂ air-to-water heat pump with a coefficient of performance (CoP) of 6.1, marking a significant efficiency improvement. The system uses CO₂ as a refrigerant and is designed for residential and commercial heating and hot water applications.

An analysis of Oʻahu's energy future argues that investing in more solar power is a better strategy than building new power plants, highlighting the island's abundant solar resource and the economic and environmental benefits of renewable energy over fossil fuel-based generation.

Scientists have developed a solid-state material that can convert sunlight into ultraviolet (UV) light, potentially enabling new applications in disinfection, medical treatments, and environmental monitoring without needing electrical power. The material absorbs visible light and re-emits it as UV light, offering an efficient and sustainable way to generate UV radiation directly from sunlight.

Starting July 1, Australia's Solar Sharer scheme will provide eligible households with three hours of free electricity daily, aiming to ease cost-of-living pressures and promote renewable energy use.

Europe is hesitant to build AI data centers in Iceland despite its abundant renewable energy and cold climate, due to high construction costs, limited infrastructure, and geographic remoteness from major data hubs.

In April, solar energy generated more electricity than coal for the first time ever on a monthly basis in the US, but the milestone applies to total generation rather than grid-supplied power, as much of the coal use that month went to industrial facilities rather than power plants.

Pakistan has experienced a remarkable surge in solar energy adoption, with imports of Chinese solar panels skyrocketing. This grassroots-driven boom, bypassing centralized grid projects, has added significant renewable capacity to the country's energy mix in a short time.

Geothermal energy, a renewable source from heat beneath the Earth's surface, is abundant but remains expensive to develop due to high upfront drilling costs. Despite its potential for constant, clean power, technological and financial barriers have slowed its widespread adoption compared to solar and wind energy.

The article discusses the "duck curve" phenomenon in California's solar-heavy electricity grid, where growing solar capacity shifts net demand into a steep evening ramp, creating operational challenges. It highlights how the duck is deepening and widening as renewable penetration increases, requiring greater flexibility from power plants and storage to balance the grid.

Geothermal energy is abundant underground but remains expensive to harness due to the high costs of drilling and technology. Despite its potential for providing constant, low-carbon power, widespread adoption is limited by upfront investment and geographical constraints.

Aptera claims its solar-electric vehicle can generate up to 46 miles of range per day from built-in solar panels, allowing many daily commutes to be powered entirely by sunlight without plugging in.

Tesla and Sunrun have partnered to create a 16-gigawatt virtual power plant (VPP) designed to supply electricity to data centers. The VPP will aggregate energy from residential solar and battery storage systems to support grid reliability and meet the growing power demands of data centers.

A 200-kilometer undersea power cable will connect Europe and North Africa for the first time, linking Tunisia and Italy to transmit clean energy across the Mediterranean. The project aims to enable large-scale renewable energy sharing between the two regions.

Utah's largest solar and battery storage project has officially come online. The facility combines solar power generation with large-scale battery storage, marking a significant step in the state's renewable energy capacity.

A Nature article reviews seawater battery technology, which can simultaneously store renewable energy, desalinate water, and capture carbon dioxide. The approach converts seawater into fresh water while sequestering carbon as solid minerals, offering a potential multi-functional solution for environmental challenges.

A solar farm built on restored peatland in the UK has seen a significant increase in wildlife, with surveys showing a rise in bird, insect, and plant species. The project demonstrates that renewable energy infrastructure and habitat restoration can coexist, benefiting both climate goals and biodiversity.

The video examines how China has transformed into a global energy superpower through massive investments in renewable energy, solar panel manufacturing, electric vehicles, and grid infrastructure, surpassing other nations in clean energy capacity and production.

European heat pumps are now replacing more than twice the amount of gas the EU once imported from Russia, with the technology's deployment surging across the continent. Norway leads in heat pump sales per capita, while countries like Poland and Italy are also seeing rapid growth. The shift is significantly reducing Europe's reliance on fossil fuel imports for heating.

Geothermal energy could provide massive, reliable, low-carbon baseload power, but remains largely untapped due to high upfront drilling costs, geological risk, and regulatory hurdles that deter investment and deployment.
