Rob Barnett, a senior clean energy analyst for Bloomberg, forecasts a 30% increase in global PV deployment this year, and double-digit growth through 2025.


Demand is pushing solar growth across the world to new heights, as Bloomberg senior analyst Rob Barnett forecasts deployment to increase by 30% this year. Total global solar deployment is closing in on 1 TW installed – an impressive milestone for the energy transition.

“The global solar picture is just staggering at this point,” Barnett told Yahoo Finance. “We are on track to install something like 250 GW of solar capacity this year.”

China is contributing the largest share to capacity growth this year, with about 108 GW of new operational PV. This is a near-doubling of the roughly 55 GW installed by China last year. The country has the world’s largest exposure to renewable energy, with 323 GW of solar and 338 GW of wind energy. President Xi Jinping aims for 1,200 GW combined by 2030, and the nation is currently ahead of schedule on that goal, said Bloomberg.

Wearable electronics, from health and fitness trackers to virtual reality headsets, are part of our everyday lives. But finding ways to continuously power these devices is a challenge.

University of Washington researchers have developed an innovative solution: the first-of-its kind flexible, wearable thermoelectric device that converts to electricity. This device is soft and stretchable, yet sturdy and efficient—properties that can be challenging to combine.

The team published these findings July 24 in Advanced Energy Materials.

Electrons find each other repulsive. Nothing personal—it’s just that their negative charges repel each other. So getting them to pair up and travel together, like they do in superconducting materials, requires a little nudge.

In old-school superconductors, which were discovered in 1911 and conduct electric current with no resistance, but only at extremely , the nudge comes from vibrations in the material’s atomic lattice.

But in newer, “unconventional” superconductors—which are especially exciting because of their potential to operate at close to room temperature for things like zero-loss power transmission—no one knows for sure what the nudge is, although researchers think it might involve stripes of electric charge, waves of flip-flopping that create magnetic excitations, or some combination of things.

News: the world’s first building to be powered entirely by algae is being piloted in Hamburg, Germany, by engineering firm Arup.

The “bio-adaptive facade”, which Arup says is the first of its kind, uses live microalgae growing in glass louvres to generate renewable energy and provide shade at the same time.

Installed in the BIQ building as part of the International Building Exhibition, the algae are continuously supplied with liquid nutrients and carbon dioxide via a water circuit running through the facade.

This research paper presents the design of a wireless power transfer (WPT) circuit integrated with magnetic resonance coupling (MRC) and harvested radio frequency (RF) energy to wirelessly charge the battery of a mobile device. A capacitor (100 µF, 16 V) in the RF energy harvesting circuit stored the converted power, and the accumulated voltage stored in the capacitor was 9.46 V. The foundation of the proposed WPT prototype circuit included two coils (28 AWG)—a transmitter coil, and a receiver coil. The transmitter coil was energized by the alternating current (AC), which produced a magnetic field, which in turn induced a current in the receiver coil. The harvested RF energy (9.46 V) was converted into AC, which energized the transmitter coil and generated a magnetic field. The electronics in the receiver coil then converted the AC into direct current (DC), which became usable power to charge the battery of a mobile device. The experimental setup based on mathematical modeling and simulation displayed successful charging capabilities of MRC, with the alternate power source being the harvested RF energy. Mathematical formulae were applied to calculate the amount of power generated from the prototype circuit. LTSpice simulation software was applied to demonstrate the behavior of the different components in the circuit layout for effective WPT transfer.
