Renewable energy smashes global records in 2015

Last year saw record worldwide investment and implementation of clean energy such as wind, solar and hydropower.


Some 147 Gigawatts of renewable electricity came online in 2015 - the largest annual increase ever and as much as Africa’s entire power generating capacity.
Clean energy investment increased to $286bn (£198bn), with solar energy accounting for 56% of the total and wind power for 38%.
Overall, more than twice as much money was spent on renewables than on coal and gas-fired power generation ($130bn in 2015), the REN21 global status reportfound.
Christine Lins, REN21’s chief, said: “What is truly remarkable about these results is that they were achieved at a time when fossil fuel prices were at historic lows, and renewables remained at a significant disadvantage in terms of government subsidies. For every dollar spent boosting renewables, nearly four dollars were spent to maintain our dependence on fossil fuels.”
For the first time, emerging economies outspent richer nations in the green energy race, with China accounting for a third of the global total. Jamaica, Honduras, Uruguay and Mauritania were among the highest investors, relative to their GDP.
African and Latin American countries also set some of the world’s most ambitious targets for clean energy deployment last year, the report says.
But the renewables revolution stuttered in many developed countries, with the significant exception of the US. In Europe, investment plummeted by 21% after the withdrawal of policy supports, such as clean energy subsidies and binding targets.
Despite this, renewables still provide 44% of the EU’s electricity capacity, and15% of its final energy consumption.

Jean-François Fauconnier of Climate Action Network Europe said the report should be a “wake up call” to the European commission, spurring increased 2030 renewable goals in a review later this year. “The EU is at risk of missing the ongoing energy revolution and lagging behind other leading economies for decades,” he said.
The UK saw a 25% rise in renewable energy investments last year, the paper finds. But figures for the first quarter of 2016 suggest this may not survive cuts to solar subsidies and a slowdown in onshore wind planning approvals.
Steve Sawyer, GWEC’s secretary general said: “A record 63.5 GW of wind power was installed worldwide in 2015, demonstrating the maturity of the sector; and showing how renewables are supplying competitive, reliable and clean energy to fuel economic growth and cut CO2 emissions.”
Around the world, 8.1million people are now employed in the clean energy industry - excluding hydropower - 3.5 million of them in China. In the US, more people now work in the solar industry than in oil and gas extraction.
While employment in the clean energy sector grew by 6% in 2015, jobs in the oil industry contracted by 18%, according to the International Renewable Energy Agency.
But the fast-maturing renewables sector still has to overcome storage limitations, and the world’s dependence on infrastructure systems geared towards fossil fuels.
Arthouros Zervos, the chair of REN21 said: “The renewables train is barreling down the tracks, but it is running on 20th-century infrastructure – a system based on outdated thinking where conventional baseload is generated by fossil fuels and nuclear power.”
A build-out of decentralised and community-based generation was urgently needed to accelerate the clean energy transition, he said.

A new future weightless Insulation material

A totally new insulation material has been developed that is totally weightless but can still withstand high temperature, that would not be tolerated by other materials and destroy it. The porous aerogel is at least 99 percent open space , with the rest made up of an atomically thin ceramic called hexagonal boron nitride. The design proves extremely durable under high temperatures and rapid temperature shifts of over 1,000 degrees Celsius.  “It’s notoriously hard to make materials that are not just lightweight, but can also be heavily heat resistant,” says Deep Jariwala, an engineer at the University of Pennsylvania.  The new ultralight insulator may be especially well suited to shielding components on spacecraft , which must endure extreme temperature swings when turning toward or away from the sun or re-entering Earth’s atmosphere, he says.  The aerogel comprises a network of tiny air pockets, with each pocket separated by two atomically thin layers ...

Scientists have created glasses-free 3D holograms using graphene

Three-dimensional holographic images are a mainstay in many sci-fi films. But in real life, we’ve struggled to achieve the same effect without the use of annoying 3D glasses. Now scientists from Swinburne University of Technology in Melbourne, Australia have used a graphene-based material to create a full-colour, pop-up, 3D floating display - visible from a wide angle with the naked eye. The effect was created using a graphene oxide, and could be applied to the touch-screen surface of smartphones or watches, the authors Min Gu and Xiangping Li explain over at The Conversation. Holograms work by bending light off the screen in a carefully controlled way so that, instead of bouncing directly back into your eye, it makes it appear as though it's projected off a separate display. The Swinburne researchers were able to create the floating 3D display by tweaking the refractive index - the measure of how much light bends as it passes through a medium - of graphene...

Top 3 Fastest Hydrogen Powered Car

When it comes to racing using hydrogen powered car, this top three car will win the show. Hydrogen powered car uses hydrogen gas as a fuel which combust with oxygen to form water. #3. Aston Martin Rapide :  British luxury marque ASTON MARTIN  introduced AM Rapide S in early 2010.  The Rapide is powered by a 5,935 cc V12 engine , producing 470 bhp and torque of 443 lbf·ft (601 N·m). It is Rear-wheel drive  and has a six- speed Touchtronic automatic. The Rapide can reach a top speed of 188.5 mph (303 km/h),  and accelerate 0-100 km/h (62 mph) in 5.3 seconds, or 0-60 mph (97 km/h) in 5.0 seconds. #2. BMW H2R : This car built by BMW uses liquid hydrogen as a fuel. The H2R’s 6.0-liter V-12 engine, which draws on BMW 's Valvetronic  and Double-Vanos  technology, is based on the 760i’s gasoline-fueled powerplant. This H2-powered high performer generates 232 horsepower (173 kW), helping it t...
