Nuclear Power: Using nuclear fission tremendous amounts of heat is generated in the reactor. Water is then used to cool the reactor which generates steam, the steam generated turns a steam turbine which generates electricity. And while a shift to renewables has begun, it still contributes around 18% of the world's total energy consumption, with only about 10% coming from modern renewables. Targets, indicators and progress SDG 7 has five targets, measured with five indicators, which are to be achieved by 2030. Three out of the five targets are "outcome targets", and two are "means of achieving targets". Target 7.1: Universal access to modern energy The first target of SDG 7 is Target 7.1: "By 2030, ensure universal access to affordable, reliable and modern energy services". This target has two indicators: Indicator 7.1.1: Proportion of population with access to electricity Indicator 7.1.2: Proportion of population with primary reliance on clean fuels and technology. A report from 2019 found that: Progress in expanding access to electricity was made in several countries, notably India, Bangladesh, and Kenya. The global population without access to electricity decreased to about 840 million in 2017 from 1.2 billion in 2010. Sub-Saharan Africa remains the region with the largest access deficit. Here, 573 million people—more than one in two—lack access to electricity. The population without access to clean cooking solutions totaled almost 3 billion in 2016 and was distributed across both Asia and Africa. Key strategies for closing this gap will include private sector financing, versatile solutions that include decentralized renewables, and efforts to both extend rural electrification and cope with urban densification. Women are disproportionately affected by indoor air pollution caused by the use of fuels such as coal and wood indoors. Barriers to the adoption of clean cooking solutions include their affordability, lack of supply, and social acceptability. According to the World Bank, 90 percent of the world's population had access to electricity as of 2018. It also noted that from the years 2010 to 2018, the global population without access to electricity went down from 1.2 billion to 789 million. An average of 136 million people had access to electricity between the years 2016 and 2018. There are strong disparities among countries and regions. For example, countries that are least developed are lagging behind the global average. Estimations note that 94% of the global population should have access to electricity by 2030, without taking
