All solar efficiency breakthroughs since 1975 on a single chart

All solar efficiency breakthroughs since 1975 on a single chart | No(n)sense | Scoop.it

The National Center for Photovoltaics (NCPV), which is part of the U.S. National Renewable Energy Lab (NREL), maintains a chart that shows efficiency records for all kinds of research solar technologies of all types (thin-film, single-junction cells, multi-junction cells, organic cells, quantum dot cells, etc). Above is the latest version as of April 2013.


On it, you can see the steady pace of progress and how different solar cell compositions compare to each other. Of course, these record-breaking cells were probably very expensive to manufacture and made only in very small quantities, so don't expect to see efficiency numbers like these in commercial PV... But over time, yesterday's record-breakers become today's mass-market products, so all this progress isn't just for the sake of breaking records either.

How Much Is the Internet's Electric Bill? [INFOGRAPHIC]

How Much Is the Internet's Electric Bill? [INFOGRAPHIC] | No(n)sense | Scoop.it
The data centers that keep the Internet running require an incredible amount of electricity every year ... and they waste most of it.

 

While surfing the web, you’re probably more concerned with the charge left on your laptop’s battery. But how much power does it require to keep the Internet itself running?

Powering worldwide data centers for major web companies like Google and Amazon is a huge undertaking. Between the servers and their cooling systems, 'data barns' consume 30 billion watts annually, about 1.5% of global electricity. And at the rate the Internet is growing and adding users, expect that to rise significantly in the next several years.

 

Are these centers being run efficiently? What toll does it take on the environment just to make sure your Facebook status (and a billion other Facebook users’) reaches the masses?

Renewable Energy Revolution: Declining Costs, Surging Capacity

Renewable Energy Revolution: Declining Costs, Surging Capacity | No(n)sense | Scoop.it

The renewable energy revolution is under way. Renewable power generation now accounts for around 50% of all new power generation capacity installed worldwide.


The combination of rapid deployment and high learning rates for technology “has produced a virtuous circle that is leading to significant cost declines and is helping fuel a renewable revolution,” according to a new global study of renewable power generation costs in 2012 produced by IRENA, the International Renewable Energy Agency, which announced it isestablishing its global headquarters in the United Arab Emirates during last week’s Abu Dhabi Sustainability Week.

 

Additions to global wind power generation capacity totalled 41 gigawatts (GW) in 2011, according to IRENA’s “Renewable Power Generation Costs in 2012: An Overview.” That’s in addition to 30 GW of new solar photovoltaic (PV) electricity generation capacity, 25 GW of hydro power, 6 GW of biomass, 0.5 GW of concentrated solar power (CSP), and 0.1 GW of new geothermal power capacity.
