Wind

Offshore wind turbines deliver a strong promise in today’s tough times of climate changes’ debate. The rapid development of the sector favors the need for new gravity concepts. Besides design, ballast is a critical element responsible for the turbine’s stabilization and therefore its success. Its quality, density, and weight, defined by the material choice and […]

More states are setting targets for renewable energy. Cities and counties are joining in. Utilities are formalizing commitments. And economics, as always, play a major role. The transition to clean energy

Energy storage is becoming increasingly important to the power industry. Lithium-ion battery technology has been implemented in many locations, but flow batteries offer significant benefits in long-duration

How will the electric grid change as the world transitions to a power system with more renewable energy resources? Some experts foresee a shift from today’s grid-type architecture to a system of systems—from the current centralized design to a distributed energy scheme. While it’s hard to know exactly what the future holds, it’s commonly believed […]

Annual wind power generation exceeded hydroelectric generation for the first time in 2019, according to data published by the U.S. Energy Information Administration (EIA) on Feb. 26, making wind the top-producing renewable source of electricity in the country, a position long held by hydro. The EIA’s Electric Power Monthly with Data for December 2019 report […]

The science of renewable energy is remarkable—the ability to harness nature to magically power our modern world is a seductive vision. And yet, the actual business of renewable energy is late to establish itself as a viable competitor to the petrochemical industry. The problem is rooted in cost parity and the challenges of production, storage, […]

A new report from a global research, data, and analytics firm says the total market for energy storage will reach $546 billion in annual revenue over the next 15 years, led by the continued electrification of the transportation sector. Lux Research, a Boston, Massachusetts-headquartered group, in its “Global Energy Storage Market 2019” report, estimates the […]

Researchers at a few prominent universities have published findings on recent power-related projects. At Cranfield University in the UK, hydrogen production technology is advancing with an eye on cost and carbon reductions; researchers at the University of Michigan released best practices for extending lithium-ion battery life; and a Massachusetts Institute of Technology (MIT) study found […]

Responding to a request from a Democrat-led U.S. House committee, the federal International Trade Commission (ITC) is investigating how New England’s increasing renewable targets are economically affecting the region, and what role renewable imports play in meeting those commitments. The ITC, an independent, nonpartisan and quasi-judicial federal agency that also provides fact-finding as it relates […]

An energy and finance research group on Feb. 18 said Siemens Gamesa Renewable Energy’s (SGRE’s) offshore wind installations make it far and away the market leader in that category, while Danish wind turbine manufacturer Vestas continues to lead the onshore and overall wind turbine market. The report published Tuesday from BloombergNEF (BNEF) said Vestas took […]
