              and man power training with an integrated approach has been rec-

           9. Urgency:
              a. World population will reach 10 billion in 2020.
              b. Half of the population will have only 20 GJ/yr.
              c. The other half in the industrialized countries will use 15 times as
                much, i.e., 300 GJ/yr.
              d. “Firewood crisis” has changed to “firewood catastrophe” and the
                                                                        2
                forest cover is diminishing globally at the rate of 250,000 km /yr.
                Energy administration in developing countries depends mainly on
                three denominators:
                (1) Growth rate of population
                (2) Energy self-reliant populations growing in size but lowest rate
                (3) Rural population largest in size, but lowest rate of energy consumption
                   in most countries

             Recommendations of new and alternative energy resources are
           available. The emphasis is on nonfossil and renewable resources,
           namely, biogas and biomass, solar active (photovoltaic), solar passive
           (preheating of water), wind, minihydroelectric, and minitidal resources.
           The major attempts for conservation include: conservation side legis-
           lation, education, awareness, management, and forecasting.
             In Europe and South America, biomass and its modification have
           been given a lot of attention as a substitute to fossil fuels. The primary
           material, of course, is the waste of different plant and vegetable origins.
           The conversions are to biogas, alcohol, and manure. Proper selection of
           waste material may lead to optimal production of the right transform.
           Advanced countries, point out that electrical power is attractive in many
           respects and that the search for renewable and infinite resources to
           produce and supplement electrical energy should continue. Hydropower,
           solar energy, wind, solid waste, biomass, geothermal energy, ocean tidal
           power, and ocean thermal gradients are a few resources that need atten-
           tion. In fact, many institutions and organizations have created demon-
           stration models for these.
             In the United Kingdom, the emphasis seems to be more on proper
           selection of local conditions and availability of the resources. Biomass and
           biogas need collection, transport, and processing to be properly useful
           for energy generation. Setting up aerogenerators, wind pumps, and
           solar heating will depend on available and favorable conditions and the
           proper location. If successfully implemented, they can reduce the local
           demand or share the load of a national power grid. The other resources
           that remain to be developed and commercialized are listed in the fol-
           lowing discussion.
