Inhabitat » Hybrid Squared: Ingenious Energy-Generating Bike Rental System - 0 views

  • Designer Chiyu Chen has conceived of an ingenious transit system that encourages the use of sustainable transportation by crediting people for renting and riding bicycles. His Hybrid2 system consists of a fleet of rentable bicycles that are capable of generating and storing kinetic energy, which is then used to power the city’s hybrid electric buses. Simply rent a bike, charge it up with kinetic energy from pedal power, and then return it to a kiosk - the station feeds energy into the city’s smart grid, and you receive a credit towards your next bus pass!

    It's not always about numbers and science. The general appeal for this idea might make it work, even though - from an engineering viewpoint - it's like trying to build a fortune saving nickels and dimes.

  • Europe could switch to low carbon sources of electricity, with up to 100% coming from renewables by 2050, without risking energy reliability or pushing up energy bills, according to a major new study, Roadmap 2050: a practical guide to a prosperous, low-carbon Europe, developed by the European Climate Foundation (ECF) with contributions from McKinsey, KEMA, Imperial College London and Oxford Economics. It says that a transition to a low- or zero-carbon power supply based on high levels of renewable energy would have no impact on reliability, and would have little overall impact on the cost of generating electricity.

  • It turns out, however, that what most environmentalists know about the future supply of natural gas and other fossil fuels is based more on industry hype than on actual data. And, that means that they are missing a key argument in their discussions about renewable energy, one that could be used to persuade those less concerned about pollution and climate change and more concerned about energy security: There is increasing evidence that no fossil fuel will continue to see its rate of production climb significantly in the decades ahead and so none of them is a viable "bridge fuel," not natural gas, not oil, not coal. This means that global society must leap over fossil fuels and move directly to renewables as quickly as possible. In advanced economies this leap must be combined with a program of radical reductions in energy use, reductions which are achievable using known technologies and practices.

  • Forty years ago, Harold Hay, 98, invented a simple, inexpensive way to heat and cool a home using the sun’s rays, but without the panels and wiring that come with conventional solar energy systems. He’s been pushing for its adoption ever since, trying to find footing in each of the solar industry’s last three boom-and-bust cycles. Yet, despite the merits of his pioneering technology, the energy establishment has shown only fleeting interest.

Sun sets on BP's solar hopes - 0 views

    Solar power will not be able to compete with conventional energy until there is a breakthrough in the technology, BP's chief executive has said, in a further sign of the company's move away from renewables towards oil and gas. BP has invested hundreds of millions of dollars in making solar cells and components, but in the past six months it has been closing factories around the world, and announced a sharp cut in its investment in alternative energies, such as solar, from $1.4bn last year to $1bn (£658m) this year. Tony Hayward, chief executive, yesterday told a conference in California: "I think solar is probably the most challenged of all of BP's alternative energy interests." He added: "It is not going to make the transition to be competitive with more conventional power, the gap is too big."

Cogeneration Can Slash Carbon and Costs (ENN) - 0 views

  • Jeff Johnson on 29 Aug 08
     
    Cogeneration of electricity and heat is one of the most promising means of using existing technologies for sustainable ends, but it is also one of the most neglected and least understood. Cogeneration can dramatically increase energy efficiency, slash carbon emissions, and save money. Using cogeneration in combination with heat-pump technology and plug-in vehicles as part of a renewable electric grid, we could say goodbye to gasoline and to coal electricity generation and have a real chance in 10 to 20 years for an 80 percent reduction in carbon dioxide emissions. This transition will not require rocket science but simply the integration of existing technologies.

Want fewer power plants? Make outdoor lighting more efficient - 0 views

shared by Colin Bennett on 05 Nov 09 - Cached
  • The proposed changes will phase out the least efficient outdoor lighting products by the end of 2012, transitioning to new lighting products that are better for the environment and less costly to run. For example, new outdoor lights will be required to have a sensor that will turn them off during daylight hours, putting an end to wasteful streetlight operation during the day. New parking lot lights must be capable of being dimmed, which can cut their energy use in half. The agreement also directs the US Department of Energy (DOE) to develop even better standards by 2013.

  • One of the most interesting parts of the book is the chapter “Tools for the Transition” Greer has a most interesting discussion of the merits of the slide-rule over the pocket calculator, and explains why it is infinitely more suitable to a low-energy world:it is durable- a solid aluminum slde-rule could last nearly geological time-scales-, independent, dependable and perhaps most significant of all its use of transparent- a future archeologist would be able to work out exactly how to use it. I have never actually used a slide-rule, but this discussion has inspired me to get one, and even teach its use on permaculture courses as an example of durable technologies. There are many other insightful observations Greer makes in this chapter, including comments on salvage and organic agriculture, and what will endure into the post-collapse world.

Is the Solar Industry Hurting the Environment? - 0 views

    Solar energy is necessary for our transition to a sustainable economy, but a recent study in Geophysical Research Letters suggests that the industry may be harming the environment. Nitrogen Triflouride (NF3), a greenhouse gas used by the semiconductor industry to clean the chambers where silicon chips are produced, has 17,000 times the globe-warming capacity of CO2. Now researchers believe that emissions of the gas are up to 4 times higher than previously thought-perhaps as high as 16 percent.
