Answer: False (the passage states it was less than 1%).
Germany has successfully integrated high levels of solar power into its grid.
Answer: True.
All forms of renewable energy are now cheaper than coal.
Answer: False (some are, but not all; the passage notes exceptions like concentrated solar thermal).
The author predicts fossil fuels will disappear by 2030.
Answer: Not Given (the passage discusses growth but makes no such prediction). Essay: Renewable Energy Dreams Become Reality – IELTS
You should spend about 20 minutes on Questions 1-13, which are based on the Reading Passage below.
From Pipe Dream to Power Grid
For much of the 20th century, the concept of powering entire nations with wind, sunlight, or water was dismissed as an environmentalist’s pipe dream. Critics argued that renewable sources were unreliable, inefficient, and economically unviable compared to fossil fuels. However, the last two decades have witnessed a paradigm shift. What was once science fiction is now a tangible global industry. Solar farms stretch across deserts, wind turbines rise from the ocean floor, and electric vehicles (EVs) charge using energy harvested from the homeowner’s roof.
The Solar Surge
The most dramatic transformation has occurred in photovoltaics (PV). In 2000, solar power was the most expensive source of electricity, costing nearly $8 per watt. By 2025, that figure plummeted by over 90%, making solar the cheapest form of electricity in history for many regions. This is not merely due to government subsidies; economies of scale and breakthroughs in materials science drove the change. Perovskite solar cells, for instance, have achieved efficiency rates that rival traditional silicon, while being cheaper to produce. Countries like China, the United States, and India are now installing solar capacity at a rate that would have seemed impossible a generation ago. The ‘dream’ of a solar-powered home is now a standard option for new constructions in sunbelt regions.
Offshore Wind: Harnessing the Gale
While onshore wind faced opposition due to noise and land use, offshore wind has exploded as a technological marvel. Modern turbines, standing taller than the London Eye, can generate enough electricity to power a home for two days with a single rotation. The UK, Denmark, and Germany have led this charge, but new players like the US East Coast are catching up rapidly. The real game-changer has been floating wind farms, which allow turbines to be deployed in deep waters where winds are stronger and more consistent. These installations are turning ‘unusable’ ocean space into the world’s most productive power plants.
The Storage Breakthrough
The Achilles’ heel of renewables has always been intermittency—the sun doesn’t always shine, and the wind doesn’t always blow. For decades, this made grid stability a nightmare. Enter the lithium-ion battery revolution, spurred by the electric vehicle industry. Massive grid-scale batteries, the size of shipping containers, can now store excess solar energy during the day and release it during peak evening hours. Moreover, new technologies like pumped hydro storage and green hydrogen—produced by splitting water with renewable electricity—are solving the seasonal storage problem. In 2024, for the first time, a major industrial region in Germany ran for 48 consecutive hours on 100% renewable energy, using hydrogen stored from the previous sunny week.
Economic Reality vs. Political Dreams
Despite the technological success, the transition is not frictionless. The International Energy Agency (IEA) confirms that renewables accounted for over 30% of global electricity generation in 2025, up from 20% just a decade prior. However, fossil fuels remain entrenched in heavy industry, aviation, and shipping. The dream of complete decarbonization by 2050 requires not just better batteries, but smarter grids, updated regulations, and unprecedented international cooperation. Critics rightly point out that mining lithium and rare earth metals for turbines and batteries has its own environmental footprint.
Nonetheless, the momentum is irreversible. Investors have voted with their wallets: for the last five years, global investment in renewable capacity has exceeded that of new fossil fuel plants by a factor of three to one. The dream, it seems, has a balance sheet. In the 1970s, renewable energy provided over 10%
What does the author say about Perovskite solar cells? A) They are less efficient than traditional silicon cells. B) They are cheaper to produce and highly efficient. C) They are only used in the United States. D) They have been abandoned due to high costs.
According to the passage, what makes floating wind farms revolutionary? A) They are cheaper than onshore turbines. B) They can be deployed in deep waters with consistent winds. C) They do not require any storage solutions. D) They are built directly inside urban areas.
The phrase "the Achilles’ heel of renewables" refers to: A) The high cost of installation. B) The opposition from fossil fuel companies. C) The problem of intermittency. D) The lack of government subsidies.
What does the investment data from the last five years indicate? A) Fossil fuels are still receiving three times more investment. B) Investment in renewables and fossil fuels is equal. C) Renewables have attracted three times more investment than new fossil fuel plants. D) No new fossil fuel plants are being built.
Note: As exact questions vary by test provider, this is a logic-based review of typical answers.
Example Question: Statement: "The initial motivation for developing renewable energy was primarily environmental." Text Reference: "The oil shocks of the 1970s drove the initial search for alternatives..." Logic: The text suggests economic/security motivations (oil shocks) were the driver, not just the environment. Answer: False.
Example Question: Statement: "Denmark has achieved 100% renewable energy status permanently." Text Reference: "Denmark aims to be fossil-fuel-free by 2050..." or "Denmark frequently generates more wind power than it uses..." Logic: If the text says "aims to" or "frequently," but the statement says "has achieved permanently," there is a contradiction in the timeframe/certainty. Answer: False.
