# How to fix тАЬOUT OF ENERGYтАЭ error on TRON Transfers?

When making TRC20 contract calls on the TRON network — such as transferring **Tether (USDT)** — you might have encountered the frustrating error:

> ❌ **FAILED - OUT OF ENERGY**

This message indicates that your transaction **lacked sufficient energy**, a key resource required for executing smart contract operations on TRON. Let’s break down why this happens and how to solve it — fast and efficiently.

***

### Common Causes of the “OUT OF ENERGY” Error

#### 1. Your Wallet Lacks Energy

Every contract interaction on TRON consumes **Energy**. If your wallet hasn’t staked TRX to earn energy or hasn’t obtained energy from external sources, it will rely on burning TRX instead. If neither resource is sufficient, you’ll encounter the error.

***

#### 2. Not Enough TRX to Cover Fees

If your wallet lacks energy, TRON tries to **burn TRX** to compensate. For example:

* Sending **USDT to an address without USDT** requires **130,285 Energy**, which costs about **27.74 TRX**.
* Sending **USDT to an address with USDT** requires **64,285 Energy**, around **13.7 TRX**.

Without enough TRX, the transaction will fail.

***

#### 3. Fee Limit Too Low in Programmatic Calls

If you're using a script or API to perform transactions and you’ve set a low `feeLimit` (e.g., 10 TRX), but the required fee is over 27 TRX, the transaction will fail due to insufficient resources.

***

### How to Fix It?

#### ✅ Option 1: Deposit More TRX

Make sure your wallet has enough TRX to cover burned energy costs. This works, but it’s **expensive and inefficient** in the long run.

***

#### ✅ Option 2: Rent Energy Instantly via [CatFee.IO](https://catfee.io/)

***
