The goal of the article is to find ways to use renewable energy sources in homes to save energy and reduce greenhouse gas emissions. The researchers found that using renewable energy can help cut down on CO2 emissions and make buildings more energy efficient. However, the main challenge is the high cost of switching to renewable energy and the difficulties in transporting and storing biomass. To overcome these barriers, the article suggests government support for using renewable energy in heating and cooling systems, as well as creating storage facilities for renewable energy.
