Current generation (current-gen) renewable technologies refer to conventional sustainable energy sources—such as solar, wind, hydro, and bioenergy—that have gained significant traction over the past two decades. These technologies have experienced significant cost reductions and efficiency improvements, making them increasingly cost-competitive with fossil fuels. Several niche areas within the renewables space, such as community solar developers and new business models in renewable energy distribution, are also covered. Most governments worldwide have implemented policies and regulations to encourage the deployment of renewable energy, such as feed-in tariffs, renewable portfolio standards, and tax incentives. Global agreements, such as the Paris Agreement, have also set ambitious targets to reduce greenhouse gas emissions, encouraging countries to increase their renewable energy capacity.
