What is the main problem with adopting new renewable resources?

The main problem with adopting new renewable resources is cost. Renewable sources of energy such as solar, wind, and hydroelectric power often require upfront investments that are more expensive than traditional sources of energy such as coal and natural gas. Additionally, these renewable sources of energy may require new infrastructure, such as wind turbines and solar panels, which can be expensive to install and maintain. Along with the cost, there may be other constraints, including a lack of reliable access to renewable energy sources or inadequate storage capacity for the energy produced.

the infrastructure is not in place, it's more expensive than non renewables, and there is not enough support from the government and economy
