Energy - Gauging the effectiveness of clean and renewable alternatives
“WETO-H2 evaluates two EU sustainable energy strategies in the light of a very long-term projection of global energy parameters and technological breakthroughs.”

The problem

A comprehensive reference document is needed to outline the situation of Europe in the long-term outlook for world energy demand, supply and price in the period to 2050. In addition, the impact various technological breakthroughs could make over the next half-century needs to be assessed. Such projections are vital for long-range energy strategy development and to support international negotiations. The projections and the evaluations will be made in a quantitative way using the POLES model – a global sectoral model of the world energy system.

WETO‑H2  Assessing future energy needs and sustainable solutions


WETO-H2 will forecast the world energy outlook for the period to 2050 to support EU energy, technology and environmental policies.

The project will:

  • Produce long-term energy demand, supply and price reference projections for the main regions of the world, focusing on European issues (renewables and CO2 emissions reductions)
  • Evaluate the consequences of technological breakthroughs on energy demand and supply
  • Consider the implications of two EU energy-environment strategies: implementation of a hydrogen-based energy system, and reduction of energy-related CO2 emissions by a ‘factor 4’

Contribution to policy development:

  • WETO-H2’s forecasts will help enhance the implementation of energy policy measures towards sustainability
  • It will contribute to long-term technology planning issues
  • Its long-term and global coverage will support climate change negotiations related to the Kyoto Protocol

Project deliverables

  • A world energy and technology reference case to 2050 – January 2004 to November 2004
