Yes nuclear energy is a future large contributor to combat CO2emissions and its role should be doubled if not tripled during this century for countries to meet the targets of reducing green gas emissions. Renewables and nuclear will then be not in competition but fully complementary in the future. Cleaner energy from fossil fuel is also needed with carbon sequestration when fully experimented.
Global warming is primarily caused by the emissions of CO2. Contrarily to energies produced from fossil fuels, nuclear energy emits almost no CO2. The use of nuclear energy for electricity production, in conjunction with renewables and with the adoption of more climate-responsible and energy-saving measures, will save a significant percentage of the emission of green house gases. Today, more than 400 nuclear power plants operating in over 30 countries produce 16\% of the world’s electricity, thus avoiding the emission of 2.5 billion tonnes of CO2 into the atmosphere. This saving equals more than 20\% of global CO2 emissions from power generation.
Coal, oil and gas sources are decreasing; global warming and climate change induce oceans increased level, desertification, extreme climate phenomena, climate refugees. Renewables and nuclear will then be not in competition but fully complementary in the future. Cleaner energy from fossil fuel is also needed with carbon sequestration when fully experimented.
To meet the challenges will take cooperation and integration on an unprecedented scale and now! Private sector engagement is essential – influencing national policy, driving business policy, and ensuring focus on sustained delivery of the policy intent.
