Questions: What best describes new wind turbines? The cost of new wind turbines is low. They take a year to build. They cannot generate much electricity. They take up a lot of space.

The answer is the first one: The cost of new wind turbines is low.

Explanation for each option:

1. The cost of new wind turbines is low. - This is generally correct as the cost of wind turbines has decreased significantly over the years due to advancements in technology and increased production efficiency.
2. They take a year to build. - This is not necessarily true as the construction time for wind turbines can vary depending on the size and complexity of the project, but it typically takes less than a year.
3. They cannot generate much electricity. - This is incorrect as modern wind turbines are capable of generating significant amounts of electricity, with some large turbines producing several megawatts of power.
4. They take up a lot of space. - While wind farms do require a considerable amount of land, the actual footprint of the turbines themselves is relatively small, allowing the land to be used for other purposes such as agriculture.

Summary: The best description of new wind turbines is that their cost is low, reflecting the advancements and efficiencies achieved in the industry.
