In less than a decade, the term “net zero” has gone from a mere scientific term to mainstream climate policy. Experts say that achieving net zero emissions before 2050 is crucial to avoiding the worst effects of climate change. So, we had to ask: What is net zero emissions really, and how could achieving it help us mitigate climate change?

Diesel fuel is often considered a dirty fuel because it involves burning crude oil, a fossil fuel with a high carbon footprint and a host of negative environmental side effects. But diesel fuel also includes biodiesel, which experts have touted as an environmentally friendly substitution for traditional diesel with a lower carbon footprint. So, we had to ask: What is diesel fuel really, and how can it help mitigate climate change?

Hydrogen is one of the most abundant and versatile elements in the universe, and it can also be used as an energy source. Although hydrogen can have a low carbon footprint and produce very few waste products, it is only as clean as the methods used to produce it. So, we had to ask: What is hydrogen really, and how can it help mitigate climate change?

Renewable energy uses natural resources that are flow-limited but naturally replenish themselves over time. We have been using renewable energy for centuries, but the 21st century has seen a massive increase in the research and development of renewable energy technologies as the climate crisis continues to worsen. So, we had to ask: What is the history of renewable energy?

Humans have been using biomass for centuries, beginning with the discovery of fire. Over the years, we have transitioned away from burning biomass directly and toward converting it into gaseous and liquid fuels. These modern forms of biomass could play a crucial part in mitigating climate change for years to come. So, we had to ask: What is the history of biomass?

Biomass energy is the energy generated from burning or converting organic sources including wood, agricultural byproducts, and waste. It has long been thought of as a sustainable alternative to traditional fossil fuels, but in reality, it may do more harm than good. So, we had to ask: What is biomass energy really, and how can it help mitigate climate change?

Green energy is a subset of renewable energy that provides the highest environmental benefits in terms of carbon dioxide (CO2) emissions and protecting our environment. It could play a substantial role in climate change mitigation. So we had to ask: What is the history of green energy?

Alternative energy sources have very low carbon dioxide (CO2) emissions and a very low impact on the environment, meaning they could play a vital role in combating climate change. So, we had to ask: What is the history of alternative energy?

Sustainable energy sources are in infinite supply and produce less carbon dioxide (CO2) emissions than traditional fossil fuels. They have come to represent a larger share of the global energy market as we look to transition away from fossil fuels. So we had to ask: What is the history of sustainable energy?

Clean energy is the generation of energy from sources that produce virtually no greenhouse gas emissions. Given the worsening climate crisis, clean energy has to come to represent a larger share of the overall energy market. So we had to ask: What is the history of clean energy?

On a per-mass basis, nuclear fusion can generate four times as much energy as nuclear fission while producing very little carbon dioxide (CO2) or radioactive byproducts. So, we had to ask: What is the carbon footprint of nuclear fusion?

Nuclear fission uses radioactive material to produce energy, a process that produces very little CO2 emissions. So, we had to ask: What is the carbon footprint of nuclear fission?

Nuclear fission involves splitting apart the nucleus of an atom to release enormous amounts of energy in the form of heat and radiation. It has evolved into our second-largest source of low-carbon energy today despite facing negative public opinion. So, we had to ask: What is nuclear fission really, and how can it help mitigate climate change?

Nuclear fusion involves combining lighter atoms to produce heavier atoms, a process that generates energy. It has yet to become a mainstream energy source due to various technological barriers but could provide enormous amounts of clean energy if harnessed fully. So, we had to ask: What is nuclear fusion really, and how can it help mitigate climate change?

Geothermal energy extracts heat from the Earth’s core to generate energy that produces little to no waste products or carbon dioxide (CO2) emissions. So, we had to ask: What is geothermal energy really, and how can it help mitigate climate change?
