Looking toward 2030, several innovations promise to redefine the landscape. Solid-state batteries, which replace liquid electrolytes with solid compounds, offer two to three times the energy density of current lithium-ion cells while virtually eliminating fire risk. If mass-produced, they could reduce battery weight by 40% and charging times to under 15 minutes.
Location: Paragraph B. "...capture energy usually lost during braking—a process known as regenerative braking..."
Hybrid Electric Vehicles (HEVs) and Plug-in Hybrid Electric Vehicles (PHEVs)—how they bridge the gap.
Explanation: Paragraph B explicitly states that HEVs "never need to be plugged into an external power source."
The final paragraph provides a realistic critique of sustainable transport. It notes that while the technology exists, the global infrastructure does not. Building nationwide hydrogen fueling grids and heavy-duty EV charging networks requires trillions of dollars. The author concludes that a mix of all three technologies—hybrids, EVs, and fuel cells—will dominate the future market. Part 3: Step-by-Step Vocabulary and Synonyms Guide
Often asks about the motivations of automakers (e.g., why they initially made electric cars—answer: to meet California law).
Look for names of researchers or organizations (e.g., "The International Energy Agency"). These are often used in "Matching Features" questions.
The system that generates electricity through a chemical reaction between hydrogen and oxygen is explicitly named the fuel cell .
: YES/TRUE. The text states they were accused of failing to promote EVs to create an impression of zero interest.
Fuel cell vehicles emit only water vapor and heat as exhaust.
The reading passage has six paragraphs, .Which paragraph contains the following information? Write the correct letter, A–F , in boxes 1–5 on your answer sheet. NB: You may use any letter more than once.
The text explicitly states the opposite of the statement.
