Comprehension Passage
The role of renewable energy in shaping the future of global energy consumption is undeniable. With fossil fuels depleting and causing significant environmental damage, the need to transition to renewable energy sources like solar, wind, and hydroelectric power is becoming increasingly critical. Countries that are early adopters of these technologies are likely to dominate the energy landscape in the coming decades. However, the shift from traditional energy sources to renewables presents several challenges, including high initial costs, technological limitations, and the need for infrastructure upgrades. In many developing countries, the lack of investment in renewable energy technology, coupled with a dependence on fossil fuels, makes this transition difficult. Despite these hurdles, there is growing awareness of the long-term benefits of renewable energy, such as reduced carbon emissions, energy security, and the potential for creating new industries and jobs. Governments around the world are beginning to implement policies to incentivize renewable energy production, but the pace of adoption varies widely depending on a country's economic stability, technological development, and political will. For a global shift to sustainable energy systems, it is essential that international cooperation, technological innovation, and financial support be prioritized. The future of energy depends on how swiftly nations can overcome these obstacles and commit to a sustainable energy infrastructure.
Which of the following challenges is NOT mentioned in the passage as an obstacle to renewable energy adoption?
1
High initial costs
2
Technological limitations
3
Lack of public awareness about environmental issues
4
Need for infrastructure upgrades
