Explanation:

Match each term to the logical context of the sentence:

1. The first blank describes the core trait of wind, solar, etc. – they are naturally replenished, so "renewable" fits.
2. The second blank refers to emissions these energy sources avoid; "carbon" emissions are the key environmental concern here.
3. The third blank contrasts higher upfront costs with lower ongoing needs; "maintenance" is the ongoing requirement that is lower than traditional plants.
4. The fourth blank refers to factors limiting how accessible these energy sources are; "availability" matches this context.
5. The fifth blank links reduced land needs to improved energy performance; "efficiency" means more energy output, so less land is needed for the same energy.

Answer:

1. Renewable
2. Carbon
3. Maintenance
4. Availability
5. Efficiency

Completed paragraph:
Resources such as wind, solar, water, and geothermal are sustainable energy alternatives because they are renewable.
In general, they are also better for the environment because they release very few carbon emissions. Although
many alternative energy plants do have higher up-front costs, they require less maintenance than traditional power
plants. Geographical location, economic status, weather, and technology are all the factors that limit the availability of
renewable energy sources. For many alternatives, such as solar, land requirements will decrease over time as energy
efficiency increases.
