EPA slush money

The newly passed Inflation Reduction Act provides $27 billion dollars to the EPA to reduce green house gas emissions. The annual budget for the EPA is $10 billion dollars. How are they going to spend all of this money efficiently. Will they have to hire and train new staff. Will they just hand out money to various groups who will return the favor with campaign contributions as was the case when Obama gave $500 million to Solyndra. This is why the criticism that the Act is just a giant slush fund for the democratic party is gaining credence. What does a government agency do when their annual budget has just increased 270%.
