Question

scientists are investigating how solar energy can be used along with other energy sources. which of these best describes why scientists are exploring the use of other types of renewable energy sources along with solar energy? the collection of solar energy is limited to daylight hours. solar energy can be transformed only into electrical energy. the collection of solar energy requires constant monitoring. solar energy is less popular than other types of energy.

Explanation:

To determine why scientists explore other renewable energy sources with solar energy, we analyze each option:

• Option 1: Solar energy collection is limited to daylight hours. This means solar energy isn't available at night or on cloudy days with limited sunlight. Using other renewable energy sources (like wind, hydro, or geothermal) that are available at different times or conditions can complement solar energy, ensuring a more consistent energy supply.
• Option 2: Solar energy can be transformed into heat (e.g., solar water heaters) and electrical energy (solar panels), so this statement is false.
• Option 3: While solar energy systems may need some monitoring, the need for constant monitoring isn't a primary reason to pair it with other renewables.
• Option 4: Solar energy's popularity isn't the main reason for combining it with other renewables; the focus is on overcoming its limitations (like intermittency due to daylight hours).

So the best reason is the limitation to daylight hours, as it creates a need for other sources to fill the gap.

Answer:

The collection of solar energy is limited to daylight hours.
