T-Mobile has announced their pledge to use 100% renewable energy by 2021. By using their new wind farm in Kansas and other renewable energy sources, the company is committed to increasing renewable energy use.

Additionally, the mobile carrier is joining RE100, which is a group of over 100 global companies who are all dedicated to reducing energy use and instead utilizing renewable energy sources.

"It’s the Un-carrier way to do the right thing by our customers, and moving to renewable energy is just a natural part of that," CEO John Legere said in a statement.

Legere also explained that the mobile carrier expects to reduce energy costs by about $100 million over the next 15 years by making the switch to green energy.

The company's first wind farm started being used in December and a second 160-megawatt contract with Infinity Renewables' Solomon Forks Wind Project is expected to be running in 2019. These two wind farms will fulfill 60% of the company's electricity needs. The remaining energy will be bought from early-stage wind projects rather than nonrenewable energy companies.

Why Should People Invest in Renewable Energy?

T-Mobile is one of many companies who is making the switch to renewable energy. It's big brand names like T-Mobile who are showing the good in using renewable energy. Unfortunately, many people don't believe in the harm nonrenewable energy is causing to the planet. But for those who do understand the impact our choices have on the planet and want to do something to help, let's talk about a few reasons everyone should make the switch to renewable energy.

For starters, using renewable energy significantly reduces energy costs. Nonrenewable energy types, like fossil fuels, are finite resources. So as they supply goes down, prices continue to increase. Luckily, renewable resources will never deplete. Because of this, as technology continues to be developed to harvest renewable sources, the cost to use them will keep going down.

Along with lower energy costs, renewable energy sources cause no harm to the planet. Energy companies and businesses that continue to use non-renewable sources are contributing to pollution and emissions of other harmful substances. This is leading to climate change and lower quality air. That alone is a vital reason to make the switch.

While not every single person is going to be able to fully utilize renewable energy, every small step helps. You can even start by insulating your home, which can save up to 30% of your heating costs and reduce CO2 emissions by up to 2100 pounds each year. So consider talking to your energy companies about using green energy and making small changes around your house to be more energy-efficient.
