Small-scale wind energy is still in the beginning phases in Germany. Yet interest in this technology is gaining traction in light of rising electricity prices and the sociopolitical direction we are heading in to invest more in renewable energies in the future.
Despite weakening policy drivers and competition from declining solar PV prices, the SMWT industry is still poised for growth. With a large amount of wind resource potential still available, plus several growing and emerging markets, the industry is anticipated to sustain itself into the foreseeable future. Click to tweet: According to a new report from @NavigantRSRCH, the global installed capacity of SMWTs is expected to grow from 176.4 MW in 2017 to 446.0 MW in 2026.
"With historically leading markets such as the United States, the United Kingdom, and China seeing declining annual installed capacities of small and medium wind in recent years, other countries such as Japan, Denmark, and Italy are emerging as forces in the distributed wind market thanks to favorable government incentives," says Adam Wilson, research associate with Navigant Research. "We're also seeing a shift with medium-sized turbines as their niche slowly shrinks as drivers continue to favor small wind turbines for distributed wind and larger multi-megawatt turbines dominating utility-scale applications."

Bruce Brown for Digital Trends: These trees do more than just add ambiance. Harnessing the wind to generate electrical energy usually brings to mind thoughts of huge land- or ocean-based wind farms consisting of huge towers with two or three blades, each more than 100-feet long, on the top. The size, weight, noise, and vibration of industrial wind turbines restrict their use to large open spaces. Newwind, a French startup, has developed a much smaller, urban-space-friendly “Wind Tree,” reports Electrek.
The Wind Tree, which produces sufficient energy to power small buildings or streetlights, is designed to connect to a nearby energy storage system. The trees are each about 30 feet tall and 26 feet in diameter, and weigh approximately 5,500 pounds. Each tree has 54 Aeroleafs mounted vertically on tree branches. The Aeroleafs are 3.2 feet high and, spinning at optimum speed, are capable of generating 65 watts each. So, a tree with 54 leaves has an energy-generation capacity maximum of 3,510 watts (3.5kW), about the same as a small home solar installation. Cont'd...
A recent university study showed SMA ShadeFix optimization produces more energy than traditional optimizers. It also utilizes far fewer components, reducing the need for costly service visits. Systems with ShadeFix optimization and SunSpec certified shutdown devices are the ideal solution for residential and commercial PV systems.
