  • Dealing with uncertainty in sustainable innovation: mainstreaming and substitution

    In this paper, innovation is studied as a set of activities that seeks to deal with uncertainty. It is argued that the very idea of innovation contains the assumption that the future is, in principle, open to change. Moreover, since innovations compete with other innovations and with existing solutions as well, the outcome of innovative activities has to remain uncertain. Innovation theories, in ...

  • Concentrating Solar Power

    Technology Overview   By collecting solar energy during daylight hours and storing it in hot molten salt, concentrating solar power technologies like power towers give utilities an alternative method for meeting peak loads. (Warren Gretz)  Concentrating solar power plants produce electric power by converting the sun’s energy into high-temperature heat using ...

  • A new light on saving energy

    Some 80,000 dynamic street lights have been installed in Europe over the past few years. Quite a modest number if you consider that there are some 91 million light points in Europe. The city of Oslo alone has 54,000 street lights. A dynamic street light is a system that tells you exactly how much energy each single luminary is using and when its lamp needs to be replaced. It adapts the light ...

  • Effect of window type, size and orientation on the total energy demand for a building in Indian climatic conditions

    Windows in a building allow daylight to enter a building space but simultaneously they also result in heat gains and losses affecting energy balance. This requires an optimisation of window area from the point of view of total energy demand viz., for lighting and cooling/heating. This paper is devoted to this kind of study for Indian climatic conditions, which are characterised by six climatic ...

  • Mirrors in Space for Low-Cost Terrestrial Solar Electric Power at Night

    ABSTRACT — A constellation of 18 mirror satellites is proposed in a polar sun synchronous dawn to dusk orbit at an altitude of approximately 1000 km above the earth. Each mirror satellite contains a multitude of 2 axis tracking mirror segments that collectively direct a sun beam down at a target solar electric field site delivering a solar intensity to that terrestrial site equivalent to ...

  • Better sight with natural light

    Since the invention of the light bulb in the late 1800s, the use of artificial light has swept the globe as a ‘must have’ in every home and office, largely due to the option for increased productivity. However, the result of having these luxuries so readily available has dimmed our desire to use natural light to the point where it has been largely neglected in the design of many of ...

  • Highly-Standardize Batteries for Express Convenience

    Batteries of any kind matters to the preservation of renewable energies. Hence, we are referring to the ways of preservation of renewable energies here, including solar and wind energy. In fact, the availability of solar and wind energy is passively argued in several times because solar energy is precisely presence in ...

  • Offshore Wind Versus Solar in the Eastern US: An Unexpected Rivalry

    Less than a decade ago, offshore wind energy and solar PV were similarly priced energy sources. Unsubsidized installed costs for both exceeded $5 per watt, or more than double that for land-based wind. Despite their cost, both technologies were seen as the best hopes for supplying urban centers with green power, especially in the BOSNYWASH (Boston-New York-Washington, DC) corridor of the eastern ...

  • Building Experience: Energy Efficient Buildings

    Issue: The development of large commercial, governmental and even residential buildings which take advantage of energy efficient design and incorporate on-site renewable energy sources could have a major impact on achieving and maintaining Kyoto targets on reducing carbon dioxide (CO2) emissions in the future. Although demonstration sites across Europe have been built, the lessons learnt in their ...
