# 12.6 Energy Data Consumption in Smart Contract

Below is a simplified example demonstrating how a smart contract can consume energy data.

```
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract EnergyDataConsumer {

    uint256 public latestEnergyValue;

    function updateEnergyData(uint256 _value) public {
        latestEnergyValue = _value;
    }

    function getEnergyData() public view returns (uint256) {
        return latestEnergyValue;
    }
}
```

In a production environment, the updateEnergyData function would typically be restricted to trusted oracle addresses, ensuring that only verified data can be submitted.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.frequencychain.org/12.-energy-data-layer-integration/12.6-energy-data-consumption-in-smart-contract.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
