Energy Statistics

ISEO and ISO are preparing a more complete energy statistics and forecasting methodology to present the total energy picture in the context of the transition to environmentally compatible sustainable economics. It allows integrated resource planning, including all new renewable options, such as the increasingly important direct and indirect solar energy, co-generation, hybrid systems, small decentralized units, bio energy, ambient temperature use by heat pumps and substitutions of muscle powered systems or vice versa, besides the conventional finite and renewable energy sources, based also on the new international Standard on Methods for Analysis of Technical Energy Systems ISO13602, tool for better energy systems analysis and comparison, based on reliable data.

The new energy data base quantifies past and future energy supplies, which are undergoing fundamental change due to the depletion of mineral resources and environmental constraints.

Millions of muscle-powered vehicles and work animals were missing in past energy statistics and thus were not part of any energy models in spite of their huge PWh order of magnitude.

A new energy statistics data base methodology and forecasting matrix is needed, which includes all energy sources in order to make complete energy planning and forecasting possible, based on all viable energy supplies, taking also into account all transport options, since transport represents one of the main energy demand sectors and hitherto worst polluters.

The statistics includes the total number of units, such as power stations, refineries, oil & gas fields, vehicles, animals etc. (some of them estimated until there are more precise data), total generation capacity, incl. CHP co-generation, total final energy delivered to the users, maximum available indigenous energy for each option, i.e. the limits of the domestic energy and energy export capability of each country, considering both the depletion of non-renewable energy resources and the ultimate limits to renewable energy harnessing.

The statistics will contain specifically the total calorific values of coal and peat for energy uses, the total calorific value of crude oil to refineries and petroleum products to energy users including power stations, the total gross calorific value of inland finite gas consumption delivered to users, including power station consumption, the total calorific value of fissile matter and net electric energy delivered from power stations. Co-generation is expressed as the total additional energy content from power stations delivered to the heat users.

Biomass is a complex matter. Partly it is commercially traded, but partly it is internally used on farms, in sugar mills, saw mills, private homes etc. Biomass includes woodfuels, agricultural energy crops & residues, municipal waste, black liquor, commercial & non-commercial, liquid & gaseous biofuels. Woodfuels include fuelwood, forestry and mill residues, energy plantations like willow, poplar, eucalyptus etc. and charcoal & pellets made from such woodfuels. Agricultural energy crops & residues include herbaceous & perennial plants like miscantus, reed grass, rapseed, bagasse, straw, stalks, husks and dung and pellets made thereof. Biogas comprises an estimate of all commercial and non-commercial sources directly used or supplied to pipelines, fuel cells stations etc. Its calorific value is part of total biomass Biogas includes landfill & sludge gas, digester gas, gasified biomass etc. as sub-products of total biomass. Biofuels (liquid) comprise all options such as ethanol from sugar cane, biodiesel from rapseed, methanol from any biomass etc. Their calorific value is part of total biomass, i.e. the liquid biofuels ethanol, methanol, biodiesel, alcohols etc. are sub-products of total biomass.

Hydrogen in liquefied or gaseous form from any sources. It is only an energy carrier. Hydrogen may come from renewable or fossil sources.

Hydropower potential can be derived from hydrological maps and statistics. The viability of possible sites as regards accessibility, distances to electricity consumers or the environ-mental acceptability are other considerations, which can be explained in an annex.

Hydro Pumping capacity helps to generate peak power. Indicate the max. potential and explain the energy sources such as excess base load power capacity, mid-day PV capacity etc. Hydro pumping capacity is indicative only because it uses electric energy solely for hydraulic energy storage and re-use in peak hours

Wave and Tidal power potentials can be derived from coastline configurations and their topography. Hydro, wave, tidal & wind power is mostly for electricity and expressed as such. Direct mechanical uses must be expressed in GW & TJ.

Wind power is including also mechanical wind pumps and mills - see wind energy potential in national wind atlases.

Geothermal Power potential must not only include natural aquifer resources, but also includes the deep-well options, which makes geothermal power available at most locations on the Earth. Quantify the geothermal power including co-generation.

Geothermal heat used directly (indirect uses see under heat pumps).

Solar power potential comprises the total solar power from PV collectors, solar thermal power generation and solar chimneys. The total potential comprises all sun-oriented roofs and other practically usable surfaces. Use average insolation figures and available surfaces in each country to arrive at an estimate of the total solar power. Apply a realistic average solar system efficiency to get the total max. solar thermal power generation capacity. The prime energy is the solar radiation which is not quantified in the statistics.

Solar Heat potential comprises all sun-oriented roofs and other free surfaces suitable for solar thermal collectors. Use the same surface figures as for solar power for hybrid solar collectors which harvest both simultaneously. Include solar pond systems, salt drying ponds and solar dryers of any kind.

Ocean Thermal Energy Conversion (OTEC) comprises tropical areas where the yield is sufficient. Besides electricity, OTEC may also produce heat and/or refrigeration. OTEC-CHP example used for cooling and farming applications see on Big Island in Hawaii. Ocean Heat (or cooling) comes from OTEC co-generation.

Heat by Heat Pumps comprise all systems using temp. differentials from air, water or soil.

Individual fossil fuel vehicles comprise individual land vehicles propelled by gasoline, diesel or any type of fossil gas (for public transport see entries below).

Electric vehicles (individual) comprise land vehicles driven by batteries and/or PV cells not for public transport (public transport see entries below).

Renewable fuel vehicles (individual) comprise land vehicles propelled by biofuels, biogas, methanol, hydrogen, peroxide etc. from renewable energy sources including hybrid vehicles using such fuels, even if the motors are electric (here not for public transport - see separate entry below).

Bicycles & Tricycles: Estimate of total population and their average daily use for practical purposes (not for sports) to be multiplied by estimated average hourly muscle energy applied.

Work Animals: the average power performed and bio energy physically applied by animals for practical purposes, such as horses, oxen, elephants, camels, sledge dogs etc. used for transport and work based on average annual mileage and moved mass with TJ equivalent.
