Colette Lewiner entered the Ecole Normale Supérieure (a leading French higher education school) in 1964 as a physics student where she passed the highest competitive examination (agregation) for teachers in France in this field in 1968. She graduated as Doctor in Physics (PhD) in March 1973.
In November 1979, after around 10 years spent as a physics researcher, she joined Electricité de France (EDF) as secretary general to the Utility's Research and Development Executive Vice President. In 1982, she moved to the Fuel Procurement Department, responsible first for fuel oil and then uranium and enrichment purchases for EDF's plants and being nominated Vice President for this department in 1987. In February 1998, Colette created the Development and Commercial Strategy Branch becoming Electricité de France's first woman Executive Vice President.
Colette Lewiner joined the Cogema Group becoming Chairman of the Board, Chief Executive Officer, of SGN Eurisys Group on March 23, 1992. She expanded this 10 000 persons top class engineering Nuclear Company internationally and in the services arena.
In 1998, Colette Lewiner joined Cap Gemini and created the Utilities Global Market Unit (electricity, water, gas). Since May 2000 and the merger of Cap Gemini and Ernst & Young, Colette was nominated Executive Vice President and Global Leader of the Sector Energy, Utilities and Chemicals (Oil, Gas, Utilities and Chemicals). In 2009, this overall sector represented around 13% of Capgemini’s total revenue (compared to 4% in 1998) and more than 11 000 people. Capgemini is ranked by independent analysts as one of the technical services (Consulting, Technology services, Outsourcing and Professional Services) leaders in this sector.
Consommation de pétrole, de gaz et d'électricité en hausse, ressources mondiales limitées: les tendances d'avant la crise en termes de sécurité d'approvisionnement en énergie étaient inquiétantes. Les investissements dans les infrastructures, nécessaires pour faire face à la demande et pour remplacer les infrastructures vieillissantes, étaient insuffisants et n'arrivaient pas assez vite. Des situations tendues entre offre et demande s'en suivirent, avec des coupures de courants et même des blackouts dans certains pays européens. En outre, la majorité des centrales électriques nouvellement construites ou en projet utilisaient des énergies fossiles, gaz notamment, augmentant la dépendance envers la Russie et générant des émissions de CO2. La crise économique et financière des dix-huit derniers mois a modifié l'équilibre entre offre et demande en Europe. Cette dernière a chuté, apaisant la situation à court terme, mais les investissements en infrastructures ont également diminué, ce qui s'avère inquiétant pour le long terme.
The pre-crisis trends on energy security of supply were worrying as consumption of oil, gas and electricity was growing and worldwide energy resources were limited. The investments in aging energy infrastructures needed to meet this demand were insufficient in volume and slow. This led to tense situations in the supply and demand balance with power cuts and even blackouts hitting some European countries. In addition, the majority of the new or planned electricity generation plants were fossil fuel fired, notably gas fueled, increasing gas supply dependency on Russia and generating CO2 emissions. The economic and financial crisis of the past 18 months modified the supply and demand balance in Europe. Demand has dropped bringing short-term relief, but investments in energy infrastructures have also decreased, which is worrying for the longer term.
