In the electricity sector, yes. Not so much when it comes to process heat and district heating.
Renewables still contribute less than 10% to the overall energy consumption in the US:

In Germany, where renewables already contribute up to 40% in the electricity sectors (13% of the overall energy consumption), the emissions in the electricity sector are still very bad with up to 600 grams of CO2 emitted per kWh while France emits only 50 grams on average. At the same time, a kWh costs around 30 cents per kWh in Germany while the price in France is half of that.

What we need is nuclear, it saves lives:

Renewables cannot and will never be able to power an industry nation unless the country in question has the possibility for large hydro power plants.
But hydro power has dramatic negative effects on nature and humans:
