In many cases, technology projects can conflict with environmental concerns. Technology can create a lot of waste, in the production of devices and energy consumption, and the increasing pace of innovation can only exacerbate these environmental problems. But there are a number of areas where this problem is seen as an opportunity, and technology is being used in the fight to protect our environment. Here are 5 examples of technology being used to powerful effect.

Technology is moving towards a state where all of our devices are connected, creating an Internet of Things. We are currently in the first wave of these devices reaching the mainstream, and this trend looks set to continue. Within this first wave are a number of devices that allow for greater control over the physical environment. For example, the Nest smart thermostat has redefined the task of heating and cooling homes, allowing for web-based control and automated optimization to reduce energy consumption.

A number of startups have launched connected lighting products, which use LED technology in a light bulb form factor with wireless connectivity. These lights can be controlled via a mobile application, allowing users to reduce energy consumption by ensuring that the lights are off even after they leave the house.

Electric vehicles have become a mainstream concept in recent years, driven by the popularity of Toyota’s hybrid Prius. Public demand for more electric car options has motivated a number of small, innovative startups to enter the auto market, despite huge capital and regulatory hurdles.
