to concerted policy efforts in major economies, including China. Governments can increase this potential by strengthening mandatory energy efficiency policies, providing targeted fiscal or financial incentives, leveraging market-based mechanisms, and disseminating high-quality information about energy efficiency. Nuclear energy provides a proven solution to meet growing energy needs around the world in addition to being extremely energy-dense compared to other renewable energy sources. Target 7.a: Promote access to research, technology and investments in clean energy The fourth target of SDG 7 is Target 7.a: "By 2030, enhance international cooperation to facilitate access to clean energy research and technology, including renewable energy, energy efficiency and advanced and cleaner fossil-fuel technology, and promote investment in energy infrastructure and clean energy technology" It has one indicator: Indicator 7.4.1 is the "International financial flows to developing countries in support of clean energy research and development and renewable energy production, including in hybrid systems". A progress update by the United Nations in 2020 found that international financial flows to developing countries in support of clean and renewable energy reached $21.4 billion in 2017. This is a twofold increase from flows committed in 2010. Hydropower projects received 46 per cent of 2017 flows, while solar projects received 19 per cent, wind 7 per cent and geothermal 6 per cent. Nuclear energy power generation requires the use of radioactive Uranium, which is not a renewable energy source and includes an extraction process that yields high carbon emissions. Whilst electricity generation is projected to increase globally from about 2.7 to 3.8 trillion kilowatt-hours from 2006 to 2030 particularly in large developing countries like India. A solution to this can be found in the oceans with up to 4 billion tonnes of dissolved uranium present with a concentration of 3 mg of U/m3. By implementing polymeric and inorganic materials, studies show the cost of uranium extraction can decrease from US$1230/kg to US$350/kg, due to these materials improving the efficiency of absorbent materials and thus the adsorption capacity. By increasing investments and research into improvements to adsorption materials, we can decrease the cost per kilogram of seawater obtained from uranium whilst decreasing the higher emission terrestrial mining alternative. Spatial and technological constraints associated with traditional nuclear plants have prevented developing countries from adopting nuclear energy. As such, compact nuclear reactors such as the FNBR (Fixed Bed Nuclear Reactor) have been developed, generating around 70 megawatts, composed of a pressurized light reactor
