How 5 Global Brands Use Renewable Energy
According to the Renewable Energy Policy Network, about 22.1% of the world’s energy needs are satisfied by renewable energy. Hydro power accounts for most of this (16.4%) and the remainder (5.7%) comes from solar, wind, biomass, and other renewable sources. While many governments are undertaking initiatives to keep the percentage share of renewable energy sources increasing, there are also some large global brands that are helping lead the charge to a greener economy. Today’s infographic covers these brands and the business moves they have made to ensure a smaller footprint. Microsoft has committed to being carbon-neutral since 2013. To help with this initiative, the company has made several 20-year deals to buy wind-generated power including from a 175 MW wind project in Illinois and a 110 MW project in Texas. Sony plans to have a zero environmental footprint by 2050, and already uses 100% renewable energy for its CD manufacturing in Austria. The company is also targeting to reduce the annual energy consumption of its products by 30% by 2020. Google has been carbon-neutral since 2007, and buys carbon credits to offset its emissions. The company plans to be eventually using renewable energy for 100% of its supply, and is 35% of the way there. They are in the process of investing $2 billion in renewable energy projects. Ikea, the furniture giant, has set 2020 as the year it plans to become 100% powered by renewable energy. The Swedish company has already committed €1.5 billion to solar and wind energy, including investment in wind farms in at least nine countries. Lastly, Walmart has committed to procuring 7 billion kWh of energy from renewable sources by 2020, and it claims it is already 32% of the way there. Walmart currently has more than 335 renewable energy projects in operation or development throughout the world. Original graphic by: Make It Cheaper

#1: High Reliability
Nuclear power plants run 24/7 and are the most reliable source of sustainable energy. Nuclear electricity generation remains steady around the clock throughout the day, week, and year. Meanwhile, daily solar generation peaks in the afternoon when electricity demand is usually lower, and wind generation depends on wind speeds.As the use of variable solar and wind power increases globally, nuclear offers a stable and reliable backbone for a clean electricity grid.
#2: Clean Electricity
Nuclear reactors use fission to generate electricity without any greenhouse gas (GHG) emissions.Consequently, nuclear power is the cleanest energy source on a lifecycle basis, measured in CO2-equivalent emissions per gigawatt-hour (GWh) of electricity produced by a power plant over its lifetime. The lifecycle emissions from a typical nuclear power plant are 273 times lower than coal and 163 times lower than natural gas. Furthermore, nuclear is relatively less resource-intensive, allowing for lower supply chain emissions than wind and solar plants.
#3: Stable Affordability
Although nuclear plants can be expensive to build, they are cost-competitive in the long run. Most nuclear plants have an initial lifetime of around 40 years, after which they can continue operating with approved lifetime extensions. Nuclear plants with lifetime extensions are the cheapest sources of electricity in the United States, and 88 of the country’s 92 reactors have received approvals for 20-year extensions. Additionally, according to the World Nuclear Association, nuclear plants are relatively less susceptible to fuel price volatility than natural gas plants, allowing for stable costs of electricity generation.
#4: Energy Efficiency
Nuclear’s high energy return on investment (EROI) exemplifies its exceptional efficiency. EROI measures how many units of energy are returned for every unit invested in building and running a power plant, over its lifetime. According to a 2018 study by Weissbach et al., nuclear’s EROI is 75 units, making it the most efficient energy source by some distance, with hydropower ranking second at 35 units.
#5: Sustainable Innovation
New, advanced reactor designs are bypassing many of the difficulties faced by traditional nuclear plants, making nuclear power more accessible.
Small Modular Reactors (SMRs) are much smaller than conventional reactors and are modular—meaning that their components can be transported and assembled in different locations. Microreactors are smaller than SMRs and are designed to provide electricity in remote and small market areas. They can also serve as backup power sources during emergencies.
These reactor designs offer several advantages, including lower initial capital costs, portability, and increased scalability.
A Nuclear-Powered Future
Nuclear power is making a remarkable comeback as countries work to achieve climate goals and ultimately, a state of energy utopia. Besides the 423 reactors in operation worldwide, another 56 reactors are under construction, and at least 69 more are planned for construction. Some nations, like Japan, have also reversed their attitudes toward nuclear power, embracing it as a clean and reliable energy source for the future. CanAlaska is a leading exploration company in the Athabasca Basin, the Earth’s richest uranium depository. Click here to learn more now. In part 3 of the Road to Energy Utopia series, we explore the unique properties of uranium, the fuel that powers nuclear reactors.
