The correct options are
A The deployment of renewable energy resources is restrained by competition with other land use patterns.
B Land competition, technology cost, performance, and other parameters have an impact on the deployment of renewables.
C Scientific innovations can lead to technical improvements and cost reductions for wider adoption into renewables.
Renewable energy sources are highly responsive to environmental, social and economic goals. However, their deployment and mass-scale adoption is hindered by several factors including the availibility of land. According to sources, renewables contribute around 2% of world's primary energy needs. They have the potential to provide energy services with near zero emissions of pollutants and greenhouse gases (GHGs). Governmental policies promoting the development and use of renewable energy sources and technologies can make a significant difference.
