Alternative Energy & Renewable Energy Generators

   
Energy and Human Ecology (Page 2).
  Since the international recognition of global warming and the creation of the Kyoto Protocol, attention has been drawn to alternative energy sources to reduce the consumption of carbon emitters such as coal, oil and gas. The latter have been conveniently and cheaply available in many countries including the UK, however, these sources are not only dirty but have a limited life. Consequently the logic is to develop alternative energy sources with the emphasis strictly focussed on renewable energies, accompanied by a diminishing reliance on fossil fuels.

Wondering what you can do?
  Many of us want to tackle the energy problem in our own way. Envocare aims to provide information but technology moves so fast and commerce and the administration move the goal posts so frequently that it is difficult to stay current. Below, are a couple of leading edge energy-focused links (quite different from each other) with ideas and information on how to participate in renewable energy generation.

 

 

 

 

 

 

  Link to Paul Norris and his alternative energy project Paul Norris, on his Alternative-Energy website, is creating a personal record of two ordinary people, with modest incomes, living in a medium sized town, trying to achieve self-sufficiency in terms of their energy needs. Started late 2005 it has developed and contains a lot of down-to-earth information for householders in the UK. While Paul is mainly concerned with domestic micro-generation the site has been augmented with a section on alternative Transport which is collated by Deb. Returning tothe site in Q1 2008, we are pleased to see that it has been updated and contains practical information which gladden the heart of any individual who wants to power their home with green energy (using PV batteries) and get an idea of the economics.
  Link to the Energy Project site The Energy Project is run by Robert Rohatensky (Regina, Canada) and comprises the development, design and manufacture of a new major system for clean, location independent and renewable electrical power generation that can be built from common materials.
The system design is managed in an nfp and open manner applying the same methodologies and principles that have made Linux and other Open Source Software projects such a success. So you can become involved: if you have an interest in donating some of your time and skill, the project is looking for resources that see the merit in the system and want to help.
  Link to Energytrace Energy Trace are educators who aim to provide current information about energy and its application in the world and to educate as many people as possible on the importance of energy conservation and efficiencies.

Overview of Alternative Energy Sources
  The majority of existing fuels produce carbon compounds as a by-product of burning and it is broadly accepted that the carbon emissions contribute to global warming. A natural consequence is to seek out alternative energy and renewable energy sources which emit less carbon.

Biomass and other Biofuels
 

Biomass fuels are traditionally derived from young plants which are harvested and suitably processed. The concept becomes attractive only when the plants are replaced at a rate equal to the rate at which they are harvested. For a brief discussion of biomass click here Biofuels: Information.
Ethanol and methanol can be biofuels (they can also be produced from fossil fuels but that negates the green benefits). Not intended for drinking but primarily to power motor vehicles in place of the conventional fuels. To learn more click here Ethanol and Methanol as fuel for motor vehicles.
Biodiesel is an important renewable fuel which has application in the context of motor vehicles. For more information click here Information on Biodiesel fuel.
An important caveat: it has become increasingly clear that there are major downsides to the use of biofuels. The problem lies with the enormous size of the demand for energy. The disadvantages include deforestation (loss of carbon sinks and risks of environmental catastrophes), loss of arable land (hence food), reducing biodiversity (extinction of flora and fauna) and social disruption. Even organic waste removal can deplete the land of essential fertilisers. However there are instances where waste can be put to beneficial use; for example agricultural waste that otherwise may be burnt, oils and fats from cooking that currently go into landfill, sawmill, building and municipal waste etc. Therefore it seems to be realistic that, on environmental grounds, the use of biomass can only contribute modestly to the reduction in the use of fossil fuels. Nevertheless this modest contribution can be valuable in the context of the diverse use of true renewables.

    For more detail on the use of ethanol, methanol and biodiesel in motor vehicles, see our Motor Vehicles page.
