In the U.S. we spend the following on tax subsidies each year: 1. Renewable energy: $7.3 billion 2. Energy efficiency: $4.8 billion 3. Fossil fuels: $3.2 billion 4. Nuclear energy: $1.1 billion The subsidy number you're referring to is calcuated by adding negative externalities related to air pollution and climate change to the numbers. Those estimates don't reflect funds that could have been spent elsewhere and it doesn't reflect funding priority.
