Car­bon diox­ide (writ­ten as CO2) releas­es from fos­sil fuels cause cli­mate change, a warm­ing of the earth that caus­es more intense heat waves, extreme weath­er, and oth­er neg­a­tive impacts on our world. How can we stop future cli­mate change? One option is to remove CO2 from the air around us. Here, we describe an orig­i­nal car­bon diox­ide removal tech­nol­o­gy called bioen­er­gy with car­bon cap­ture and seques­tra­tion (BECCS). BECCS pro­duces ener­gy from plants, grass­es, or trees while remov­ing CO2 from our atmos­phere. Sci­en­tists are just begin­ning to under­stand the role that BECCS can play in reduc­ing cli­mate change. We describe recent research that shows how the world might build elec­tric­i­ty sys­tems – a net­work that deliv­ers elec­tric­i­ty to your home – that remove, rather than release, CO2. These sys­tems are very dif­fer­ent from our cur­rent elec­tric­i­ty sys­tems, which use large amounts of fos­sil fuels.
