Is Tesla Really the EV King?

by Neal Dikeman, chief blogger, Cleantech Blog Tesla Motors (NASDAQ:TSLA) has been the electric vehicle darling since almost the day it launched.  I’d argue there are some really neat aspects to its product and strategy, but it is far from a resounding market leader in EVs.

Forward Osmosis – Solving Tomorrow’s Water Challenges Using Nature’s Remedy

Nature has an ingenious way of extracting water, but does it have the potential to solve many of today’s global water challenges? Before going into more details on how nature’s way of extracting water can help cut energy usage in water treatment processes, an appreciation is needed of why energy reduction in water treatment is an […]

CJK: Solving PM2.5

In spite of the political posturing taking place between Japan and Korea and China, the governments are actively working to address this challenge. Hosted by Ministry of Environment of Korea, the Environmental Ministers Meeting among Korea, China and Japan at the end of this April to implement an initiative on enhancing environmental cooperation and dialogue.

Seafloor Carpet Turns Surf’s up to Lights On

At the University of California, Berkeley, a team of engineers is pioneering ocean-source energy technology by using “carpet” to capture the energy generated by ocean waves. The team, which includes wave energy guru and Assistant Professor Reza Alam, and Ph.D. Marcus Lehmann, an engineering researcher, aims not only to capture the kinetic energy contained in […]

Boeing’s SBRC Makes Biofuel from Agricultural Rejects

A decade ago, biofuels were considered the Holy Grail of combustion-engine fuels. Measurably cleaner than fossil fuels, they were the proverbial light at the end of the tunnel, at least according to some clean energy experts. Fast forward to 2008, when the biofuel industry’s withdrawal of food crops such as corn, rice, wheat and palm […]

Cliff Majersik, IMT, Identifies Efficiency as Energy’s Biggest Asset

The Institute for Market Transformation (IMT) is a Washington, DC-based nonprofit working in the areas of energy efficiency, green building, and environmental protection. Much of IMT’s effort goes toward correcting inadequacies in the construction/remodeling vertical that prevents investors from taking a stake in energy efficiency and sustainability in the United States.

LEED v4, the Evolution of Green

It’s particularly troubling to those of us watching the energy efficiency marketplace to see one program or another take a hard hit. That’s why the 2010 class action lawsuit by Henry Gifford against the US Green Building Council – the parent organization of LEED (Leadership in Energy and Environmental Design) – had such wide-ranging responses […]

Silent Guardian: Drones without the Scare Factor

Over at Bye Aerospace, Inc., Founder George Bye and colleagues are designing drones. But don’t worry. The Denver, Colorado company, founded in 2007, isn’t the site of the next Evil Empire, and the drones which will eventually start going out the door (here or elsewhere, but not under their own power) are meant for peaceful […]

Time running out for CleanTech Revolution means more pressure for BlueTech Innovation

Has a Cleantech crash spurred the need for Bluetech innovation?

The recent CBS 60 Minutes documentary, The Cleantech Crash, was an apocryphal tale of wasted government funding and failed companies, and left one feeling sorry for a much maligned Vinod Khosla, deemed to be a prime architect behind the ‘failed cleantech revolution’. Khosla has rallied with a strong and stirring rebuttal in open letter to CBS. Cleantech, (if narrowly […]

Eco Pro 2013

Every year, Eco-Pro features a particular theme. With the recovery of Fukushima on everyone’s mind and the uncertainty in fossil fuel supply, the focus on 2013 was on renewable energy. In July 2012, the government of Japan introduced a feed-in tariff (FIT) to promote energy generation from renewable resources including solar, wind, geothermal, and biomass

Skyonic, It’s Not Your Parent’s Carbon Capture Technology

It should come as no surprise to those of us who follow environmental issues vis-à-vis climate and pollution that Norway this week walked away from the longest-running and most disappointing carbon capture plant in the world. Norway, sadly, is not the first, but its abandonment of Mongstad follows a familiar pattern of enormous hope and […]

Smart Cities

Two events I attended this month brought home the importance of cities as centers of solutions for urban sustainability and climate change. In the absence of a global agreement to limit greenhouse gas emissions, cities around the world have already made efforts to decarbonize their economies. Global networks like the C40 include energy and climate […]
