CONTEXT
 

The energy equipment sector has been selected for its widespread potential for environmental improvement. Energy industries account for 31.9 % of European GHG emissions (European Environment Agency 2009). The European Council in 2007 adopted ambitious energy and climate change objectives for 2020 - to reduce greenhouse gas emissions by 20%, to increase the share of renewable energy to 20%, and to make a 20% improvement in energy efficiency all of which require ambitious structural change for the energy supply chain.

ENVIRONMENTAL ISSUES

The Renewable Energy sector includes various production technologies, each with sector specific environmental issues.

Wind power: Predominant production phase, then, the construction of foundations.

Eco-design sources/levers: choice of materials for production; improvement of turbine performance and recovery of blades during the end of life (matter, energy).

Photovoltaic: Manufacture of panels and by-products (Cd, Pb + heavy metals).

Eco-design sources/levers: choice of materials for production; Integrated Life Cycle Thinking for energy consumption (Energy Pay Back Time).

Biogas: Pollutants during combustion of the biogas; methanation and purification steps GHG emissions.

Eco-design sources/levers: limit biogas losses in purification units; study the substituted fossil pathway.

Geothermal: Drilling phase (especially for EGS - high energy); degradation of soil and groundwater quality.

Eco-design sources/levers: extract heat sustainably (balance between extraction and recharge); avoid interference between several geothermal installations.

Thermal solar: The use is predominant (energy auxiliary).
