Types of LEDs — More than You Think

Posted: 09 Jul 2012 07:00 AM PDT

While the intro on LEDs in this post, and maybe more, may be a bit basic for some of our readers, I found this pitched guest post quite interesting and I learned quite a bit about LEDs from it, so thought it would make for a good CleanTechnica share — check it out:

Today, most people think of LEDs as those little dome-shaped lighting devices that put out just enough light to back-light a watch. While you would have been correct 10 years ago, LEDs have come incredibly far in the past decade. Not only that, but today’s LEDs are no longer sold only as individual little diodes used as an indicator light on your lawnmower, but as energy-efficient, long-lasting general replacement bulbs for many common incandescent light sources. Today, people are using LEDs for everything from lighting calculator screens, to lighting basketball arenas. Here are a few new types of LED items that you might not be aware of, and even the casual environmentalist would love.

LED Strips:

These innovative light strips consist of high-powered LEDs mounted on a super-thin flexible circuit board with an adhesive coating on the back. People use these LED strips for everything from accent lighting for their vehicles, to under cabinet lighting in their kitchen, and even for general lighting for rooms!

LED Bulbs:

Gone are the days where you have to be an electrician and possess a working knowledge of ohms and resistors to use LEDs. Today, using LED technology is as simple as screwing in a light bulb. With a wide assortment of common lighting, including MR16s, PAR type flood/spot bulbs, and standard 60W-equivalent LED bulbs (which achieve an incandescent 60W bulb’s brightness while only consuming 9W of power) available today, these easy-to-use and easy-to-install LED bulbs are powering the wider adoption of LED technology.

Automotive LED Bulbs:

That’s right, even your vehicle now can benefit from long-lasting, durable LED technology. LEDs turn on faster, have more color, and last way longer than standard automotive bulbs. Like standard household replacements, these Car LED lights generally just fit into the pre-existing socket.

Although these are the main categories consumers are adopting the fastest, there are other areas as well, including landscaping lighting, general accent lighting, and marine and RV lighting. There is good reason to adopt these technologies. According to the U.S Department of Energy: “Widespread use of LED lighting has the greatest potential impact on energy savings in the United States. By 2027, widespread use of LEDs could save about 348 TWh (compared to no LED use) of electricity: This is the equivalent annual electrical output of 44 large electric power plants (1000 megawatts each), and a total savings of more than $30 billion at today’s electricity prices.” As you can see, there is good reason people across the country are quickly taking to LEDs as their go-to light source.

Cleanweb Sustainability Hackathon Wrap-Up

New Yorkers Get Government-Sponsored Hackathon to be more Sustainable

By Tayyab Shaikh

Last weekend, the Mayor's Office and NYC Digital hosted the first Cleanweb Sustainability Hackathon at NYU-Poly in Downtown Brooklyn. Over 100 programmers, developers, and business strategists created teams and competed against one another to build applications or web startups to make sustainable choices easier for New York City residents.

The event kicked off with words of advice from Rachel Sterne, the Chief Digital Officer of the City of New York, and Tyler Mincey, the Co-Founder of Brooklyn Beta.

The city provided several newly released data sets along with the over 1000 data sets already available for public use from the NYC Open Data Portal. Representatives from technology and API partners such as Bitly, Facebook, Foursquare, Google, Mapbox, Meetup, Temboo, Tendril, Tumblr, and Twitter were on-hand both days to provided support directly to the 13 competing teams.

After 30 hours of grueling work, a panel of judges comprised of various startup and city government professionals evaluated the apps and online tools, and awarded prizes to teams in 5 different categories:

Taking the top prize and title of Judge's Pick: Green, Greener, Greenest – an online competition between each neighborhood to see which is the greenest.

Winning the award for Best App for Recycling: GreenCan – an app that will let users locate the nearest public recycling trash can, provide info on recycling non-standard items such as electronics, and provide feedback to NYC gov't regarding recycling initiatives.

Winning the award for Best App for Transportation: BikePool – an app to find people who commute via bike on the same path as you and start riding with them.

Winning the award for Best App for Crowdsourcing: ReBounty – an app that makes finding free stuff more visual, interactive and easier.

Winning the award for Best App for Parks and Public Spaces: FreshFixNYC – an app that locates farmers markets and lists available products and green farmers.

The public will vote on the City of New York's Facebook Page to decide the sixth and final prize, Popular Choice.

Other awesome ideas included:

Reinvent Lots – a web-based app to create discussion regarding the vacant lots around the five boroughs.

Clean Founders League – a social network with a competitive platform to encourage clean founders to solve the city's most pressing sustainability issues.

Adopt a Tree – an app that allows people to adopt and care for available trees form the Million Trees NYC Program. People can log their activity and post photos of their progress.

Congratulations to all the teams that participated, and the time and prizes donated by private and public sponsors this weekend!

SolarCity: 300 Jobs Openings Across the US

Posted: 08 Jul 2012 12:06 PM PDT


SolarCity dropped us a note a few days ago that it has 300 job openings across the US, in a variety of different positions (of course). I thought some of our solar-loving readers might be interested in some of those openings, so just passing that along. :D

You can check out the solar job openings here.

Some other rather interesting notes from the email:

“SolarCity hired 100 new employees in June–or about five hires every work day. Total workforce, built in six years: more than 1,900. We serve 14 states plus D.C.”

Pretty impressive.

Overall, the US has about 100,000 jobs in solar industries. Of course, I’m sure this pales in comparison to Germany or Italy, but it’s a lot more than we had 5 years ago!
