# Tron Energy Mode
Tron Energy Mode is a resource management mechanism in the Tron blockchain that allows users to reduce or eliminate transaction fees by obtaining Energy and Bandwidth. Cregis offers an enhanced Tron Energy Mode, helping users save an average of 30% in transaction fees by providing cost-effective access to these resources. Each time a Tron transaction is sent, if the address lacks sufficient available resources, the transaction will proceed using energy mode.
## Pricing of Cregis Tron Energy
Energy Fee = Energy X Price (420 SUN) / 10^6
Bandwidth Fee = Bandwidth X Price (1000 SUN) / 10^6
## Use Tron Energy in Cregis
Tron Energy Mode is activated automatically when a user has a tron transaction to proceed. There are 3 ways to use Tron energy in Cregis.
1. Burn the Tron Energy in your address When you have energy in your address, the system will prioritize using the energy available in your address.
2. Spend your account balance to purchase the Tron energy. If there is no energy in your address, the system will check your account USD balance. If your account has sufficient USD to cover the energy fee for this transaction, the system will automatically calculate the required amount in USD for you.\
Please be reminded that account balance can only apply to Team Account.
After sent, you can view the purchase record in your "Account fees".
3. Spend TRX to purchase the Tron energy If there is no energy and no USD in your account balance, you will need to spend TRX to purchase Tron energy. The system will help you the calculate the required TRX automatically.\

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://support.cregis.com/3.-wallet-and-risk-control/transaction/tron-energy-mode.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
