What are energy startups?

In the world of startups, "energy" refers to companies focused on how we generate, store, distribute, and consume power. These startups are the trailblazers at the forefront of reimagining our energy systems.

They're not just looking to make energy cleaner and more sustainable; they're also diving into how to make it smarter, more efficient, and more in tune with our modern needs and environmental responsibilities.

Energy startups often operate at the intersection of innovation and sustainability, exploring areas like renewable energy sources (think solar, wind, and hydro power), energy storage solutions that make renewables more reliable, and smart grid technologies that optimise the flow of electricity.

They're driven by the urgency of climate change and the global need to reduce carbon emissions, but they're also motivated by the opportunities presented by new technologies and changing markets.

Octopus Energy has made waves with its innovative tariffs and use of technology to make sustainable energy sources more accessible and affordable for consumers.

One of the standout features of Octopus Energy is its embrace of technology to improve the energy experience.
