PTE Speaking practice questions in the real exam format and timing.
Solar energy has become the fastest-growing source of electricity worldwide, driven by falling costs of photovoltaic panels and supportive government policies. In many regions, building a new solar farm is now cheaper than operating an existing coal plant, accelerating the shift away from fossil fuels across entire power systems.
Nuclear power generates electricity without producing direct carbon emissions, making it attractive as a tool against climate change. However, concerns about radioactive waste disposal, the risk of catastrophic accidents, and the high construction costs of new reactors continue to fuel public debate about its role in future energy strategies.
Energy storage technology is critical to the success of renewable power because wind and solar output fluctuates with weather conditions. Advances in battery chemistry, particularly lithium-ion and emerging solid-state designs, are gradually making it feasible to store surplus energy and release it during periods of peak demand.
The difficulty with wind and solar power has never been generating electricity cheaply. It is that the sun sets and the wind drops, and demand does not. Storage, rather than generation, is now the problem on which the transition largely depends.
