Eyeballing this IEA report, globally there's about $600 billion per year spent on renewables, battery storage, and nuclear: https://www.iea.org/wei2018/ https://www.iea.org/wei2018/ And let me assure you they have lobbyists. Meanwhile, you have $10 billion to spend, once. It isn't an annual flow of money. More renewable investment is helpful! But I fail to see how oligarchs could solve the problem as simply as you suggest simply by investing in renewables and lobbying.
