Best economic method to harvest the solar energy:-

Options

A. Solar cell
B. Energy plantation
C. Cultivation of sugarcane, then energy obtained by burning it
D. Solar cooker

Answer

To determine the best economic method to harvest solar energy from the given options, we can analyze each method step by step:

### Step 1: Understand the Options
We have four options to consider:
1. Solar Cell
2. Energy Plantation
3. Cultivation of Sugarcane
4. Energy obtained by burning it
5. Solar Cooker

### Step 2: Analyze Each Option
- **Solar Cell**: This method uses photovoltaic cells to convert sunlight directly into electricity. While effective, the initial investment and maintenance costs can be high, making it less economically favorable for large-scale energy production.

- **Energy Plantation**: This involves growing plants specifically for energy production. Plants can convert solar energy into chemical energy through photosynthesis, which can then be harvested as biomass. This method is generally more cost-effective and can be deployed on a large scale, providing storable energy.

- **Cultivation of Sugarcane**: This is a specific type of energy plantation. While sugarcane can be used for biofuel production, it is not the most efficient or economical method compared to broader energy plantation practices.

- **Energy Obtained by Burning**: This refers to burning biomass or fossil fuels to generate energy. While it can be effective, it is not sustainable and has negative environmental impacts.

- **Solar Cooker**: This device uses sunlight to cook food. While it is a useful tool for small-scale cooking, it does not provide a significant amount of energy for larger applications.

### Step 3: Conclusion
After analyzing all the options, the best economic method to harvest solar energy is **Energy Plantation**. This method is cost-effective, scalable, and provides energy in a storable form, despite requiring a larger land area.

### Final Answer
**Energy Plantation** is the best economic method to harvest solar energy.
