Often referred to as one of the last untapped natural resources, tidal and wave energy are known to have a large generating potential while promising one of the lowest levels of carbon dioxide emissions. So we had to ask: What is the carbon footprint of tidal and wave energy?

Biogas is a combustible gas created by anaerobic decomposition or thermochemical conversion. It is a subset of biomass that some say is more sustainable and has more greenhouse gas (GHG) reduction benefits than solid biomass. So we had to ask: What is the carbon footprint of biogas?

Solar energy is one of the most in-demand renewable energy sources that converts energy from the sun into electricity. And thanks to this harvesting of solar radiation, it also comes with low levels of greenhouse gas (GHG) emissions. So we had to ask: What is the carbon footprint of solar energy?

Wind energy is one of the fastest-growing renewable energy sources that promises the lowest levels of carbon dioxide (CO2) emissions. So we had to ask: What is the carbon footprint of wind energy?

Geothermal energy is a sustainable energy source that uses heat from the earth’s core and produces little to no waste products while promising one of the lowest levels of carbon dioxide (CO2) emissions. So we had to ask: What is the carbon footprint of geothermal energy?

Biomass is a renewable energy source that some assert can be used to reduce global carbon dioxide emissions. However, in reality, it may do more harm than good. So we had to ask: What is the carbon footprint of biomass energy?

Fracked gas refers to natural gas that is acquired through the process of fracking, forcing water and chemicals deep underground to break rock formations and release natural gas to the surface. Fracked gas is often referred to as the cleanest burning fossil fuel, and it is responsible for a large portion of the world’s electricity generation. So we had to ask: What is the carbon footprint of fracked gas?

We have relied on oil for transportation since the mid-1900s. But, at the same time, the oil industry is responsible for emitting billions of tons of carbon dioxide into our atmosphere every year. So we had to ask: What is the carbon footprint of oil energy?

Natural gas is often referred to as the cleanest burning fossil fuel, and it is responsible for a large portion of the world’s electricity generation. But it is a fossil fuel nonetheless. So, we had to ask: What is the carbon footprint of natural gas?

Fossil fuels (coal, oil, and natural gas) are the world’s primary energy source. But they are also responsible for emitting billions of tons of CO2 emissions into our atmosphere every year. So, we had to ask: What is the carbon footprint of fossil fuels?

Nuclear power uses radioactive material to produce electricity. Although the operation of nuclear power does not produce carbon dioxide (CO2) emissions, emissions can still be found during other stages of its life cycle. So, we had to ask: What is the carbon footprint of nuclear power?

Hydropower is a sustainable energy source that can reduce the effects of global warming by limiting global GHGs. However, no energy source is without flaws and hydropower has been shown to still produce GHG emissions. So, we had to ask: What is the carbon footprint of hydropower energy?

Coal has been the staple energy source in the world’s energy production since the Industrial Revolution. But considering the growing concern over climate change and our increasing carbon dioxide emissions, we had to ask: What is the carbon footprint of coal energy?

Carbon offsets have surged in popularity in the 20th century, with some claiming them as being a solution to climate change. But how much credit do we have to give those companies offsetting their carbon emissions? Or are they just using carbon offsets as a form of greenwashing?

Carbon offsets are often shown as a way to reduce greenhouse gas (GHG) emissions and our carbon footprint, thereby ensuring a sustainable planet for future generations. But as with all things, they are not without limitations. They have surged in popularity in the 20th century, and some even tout them as being a solution to climate change. So, we had to ask: What are the biggest carbon offsetting limitations?
