The United Nation Environmental Program, UNEP, has just released the summary for policy makers on Green Energy Choices: the benefits, risk, and trade-offs of low-carbon technologies for electricity production. Introducing the summary are Janez Potocnik and Ashok Khosla—the two
co-chairs of the International Resource Panel (IRP). They concluded that the demand for energy is expected to double over the coming decades in order meet the needs of a growing and a developing global population. Responding to this demand will require significant investment over the next 20 years, as they highlighted.
Achim Steiner, UN undersecretary-general, and UNEP Executive Director, assured that renewable energy is a cornerstone of a future of human prosperity without environmental sacrifice and that the international community has recognized this. In his foreword of the summary, he mentioned that through the UN secretary-general’s “Sustainable Energy for All Initiative (SE4All)”, governments and stakeholders across the globe have demonstrated a commitment to ensuring universal access to affordable, reliable, and modern energy services by 2030, while increasing the share of renewable energy in the global energy mix.
This important summary briefly presents available technologies in producing power from different sources, coal and natural gas, hydropower, wind power, concentrated solar power, photovoltaic power, and geothermal power. It presents a comparison between these sources and the impacts of each on people and on ecosystems. It also suggests scenarios for future global energy mix.
