What is the primary renewable power source that has gained popularity due to lower installation costs?

Solar power is recognized as the primary renewable energy source that has experienced a significant surge in popularity, largely due to a marked decline in installation costs over recent years. This decline can be attributed to advancements in technology, improved manufacturing processes, and economies of scale, making solar energy more accessible to both residential and commercial users.

Solar power systems, particularly photovoltaic (PV) panels, have become more efficient, and the cost of solar installations has dropped considerably. As a result, there has been an increase in the number of people and businesses adopting solar energy, contributing to the wider transition towards renewable energy sources. This trend is further motivated by government incentives and growing awareness of the importance of sustainable practices in combating climate change.

While wind power, geothermal energy, and hydropower are also important renewable sources, their installation costs and market penetration rates have not seen the same level of decrease or growth in popularity as solar energy in recent years. Each of these energy sources plays a crucial role in the renewable energy landscape, but solar power stands out for its rapid adoption facilitated by lower costs.
