Wind is a form of solar energy caused by a combination of three concurrent events:
1. The sun unevenly heating the atmosphere
2. Irregularities of the earth's surface
3. The rotation of the earth.
Wind energy offers many advantages, which explains why it's one of the fastest-growing energy sources in the world. Research efforts are aimed at addressing the challenges to greater use of wind energy.
Wind turbines work on a simple principle: instead of using electricity to make wind-like a fan-wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.

▶1. The Future of Wind Turbines ? No Blades, Vortex
The Vortex is a new kind of wind turbine being developed without any blades.
A Spanish company called Vortex Bladeless is proposing a radical new way to generate wind energy that will once again upend what you see outside your car window. Their idea is the Vortex, a bladeless wind turbine that looks like a giant rolled joint shooting into the sky. The Vortex has the same goals as conventional wind turbines: To turn breezes into kinetic energy that can be used as electricity. But it goes about it in an entirely different way. Instead of capturing energy via the circular motion of a propeller, the Vortex takes advantage of what’s known as

▶ 2. Residential Turbine Design Inspired by Hummingbird Wings
Tyer Wind turbine mimics the figure 8 flapping motion of hummingbirds.
- one of nature's most energy efficient flyers -
As unconventional wind turbines go, the flapping machine introduced by Tunisian company Tyer Wind is on the far edge of quirky. Employing dual oscillating blades that mimic the figure-8 motion of the wings of a hovering hummingbird, the turbine's relatively compact design make it a potential fit for residential use. Tyer Wind machine is claimed safer for migrating birds compared to conventional three-blade, horizontal-axis wind turbines. For the Tyer Wind machine's inventor, Anis Aouini, this isn't the first unorthodox wind converter design.

▶ 3. Autonomous Flying Wind Turbines Generate Energy at Nearly Half the Cost - Kitekraft
German startup Kitekraft is developing flying wind turbines that require 10 times less materials to develop than traditional wind turbines. The company just announced successful flight tests, which it describes as a "major milestone towards our first 100kW product."
On its website, Kitekraft explains that the reduced requirement for materials for its flying turbine - which uses a tether instead of a huge tower - means it can reduce the costs of its energy to almost half of that produced by traditional wind farms at megawatt scale. Its carbon footprint is also lower than that of standard wind turbines, the company says, partially due to the fact that large wind turbine towers are typically transported by road.

▶ 4. Silent Wind Turbines with Style to Spare - Flower Turbines
A new style of silent wind turbine doubles as an art installation that wants to overcome objections that turbines are ugly.
The turbines are designed to resemble colourful tulips, and to run silently, eliminating many of the issues with their use in urban areas.
An often-voiced opposition to wind turbines is that they are unattractive and noisy. But what if wind turbines could be turned into silent works of art? That is the goal of Flower Turbines, which aims to democratise green energy by making turbines that people actually want to live and work next to. Flower Turbine uses a Savonius-type design - a simple, drag-type device consisting of two or three scoops.

▶ 5. A Wind Turbine That Fits In Your Backpack - Shine
A portable wind power generator that can be loaded into a backpack and instantly generate electricity to charge when the battery of a mobile phone, tablet, or camera is running low.
The blades are designed to rotate in the wind direction when folded into the turbine body. When installed in a place where there is no electricity, it can generate 40KW of electricity per hour on its own, and it produces enough power to charge up to 4 mobile phones per hour. Recycle up to 85% of end-of-life parts.
