  • An online marketplace will let U.S. homeowners to evaluate selections for going solar as easily as they can compare prices for airline tickets for the first time this December.

    Geostellar is a startup backed by power producer NRG Energy Inc. It is in quest of becoming the Expedia or Orbitz of the solar industry. The said solar industry is a one-stop shop where consumers can not compare the benefits of leasing solar panels versus buying them outright alone but eventually sign up to install a system.

    On the site,, Solar players together with NRG, No. 1 U.S. installer SolarCity Corp, Boston-based solar loan provider Admirals Bank, manufacturer and financier Conergy, East Coast installer Roof Diagnostics and Connecticut’s Clean Energy Finance and Investment Authority will feature their products.

    Geostellar looks forward to its platform will let installers and financiers to lower the price of getting hold of new customers. It is a main objective in the ferociously competitive rooftop solar industry. Solar companies are centered on cutting prices therefore they will be able deliver on their promise to save customers money on power bills by converting to solar.

    Geostellar will make money by claiming a portion of a system’s total installed price – between 10 and 20 percent, Chief Executive David Levine said.

    According to Levine, Geostellar, which was founded in 2010, got its start by selling data to solar companies that showed the solar energy potential ...

  • Reducing the emission of GHG (Engineering)

    Community, Environmental Design


    Depending on which organization we are talking about, there are varying technical and operational procedures required to reduce the emission of GHG. The International Council on Clean Transportation released a long list of recommendations that would reduce the GHG emission (Appendix I), while IMO through the Marine Environment Protection Committee (MEPC) identified different classifications for the same purpose.

    On April 9, 2009, the MEPC released its second IMO GHG Study. In the study, MEPC identified four categories of options to reduce ships emissions, namely:

    • Improving energy efficiency, that is, burning less fuel to attain the same output by optimizing the design and operation.

    • Exploring renewable energy sources (sun and wind).

    • Using emission-reduction technologies (chemical conversion, capture and storage)

    • Using fuels that produce less emissions (natural gas and bio-fuels)

    Improving energy efficiency through boiler design and operation

    Optimizing ship design

    The design technology is categorized as short to medium term; it has to be inputted during construction of new ships. However, some of these optimization steps can be applied to existing ships. Each new vessel’s design specifications, such as ship’s size and the targeted speed, are considered the main hurdle toward achieving the optimal energy efficiency for the ship. Furthermore, some ports and rivers may impose limitations on the ship’s draught which further reduces its efficiency.


The challenge to achieve these worthwhile goals goes hand-in-hand with our efforts to develop sustainable sources of energy
