amber-api 2.1.0

//! # Example
//!
//! Obtain the current renewables data with minimal parameters.
//!
//! This example demonstrates how to retrieve the current percentage of
//! renewable energy in the grid for Victoria, which defaults to a 30 minute
//! block.
//!
//! # Run this example
//!
//! ```console
//! cargo run --example renewables
//! ```
