3.3 Dealing with climate: Carbon budget
Author: Lloyd Alter ABSTRACT: The carbon budget is a simplified method of estimating the maximum emissions that can be added to the atmosphere to keep under a given temperature rise. MAIN: The Carbon Budget is a target that starts with the “simple idea”, as Zeke Hausfather of Carbon Brief calls it, that “the amount of…

5.4 Energy Sources: Wind Energy
Author: Junhao He ABSTRACT: Wind energy is a renewable energy source that is clean, cost-effective, and pollution-free. It is generated by wind turbines through the process of converting the kinetic energy of wind into electricity. MAIN: Wind energy technology presented a substantial improvement over the past few years. Besides developing an eco-friendly environment, wind energy…

5.5 Energy Sources: Biomass
Author: Chenjing Zheng ABSTRACT: This presentation discusses biomass energy which has become a possible alternative source to avoid or mitigate the global consumption of fossil fuel which could help nature preservation attempts implemented by public authorities. MAIN: The term biomass energy refers to the energy that comes from renewable organisms, particularly plants and animals. This…

5.6 Energy Sources: Hydro
Author: Sabrina Thomason MAIN Hydroelectricity is produced when water falls from a higher point to a lower point creating speed and kinetic energy. The moving water is channeled through an intake canal and used to spin a turbine. The rotation winds a generator that transforms this movement into electricity that is sent out into the…

5.8 Energy Sources: Nuclear Energy
Author: Laura Oliveira ABSTRACT: Nuclear is a low carbon energy source that uses nuclear reactions and radioactive elements to generate energy and produces little greenhouse gas emissions. MAIN: After the first drop of an atomic bomb in WW2, interest in nuclear energy and power grew and technology began to advance alongside the fear of nuclear…

6.1 Materials: Cement and Concrete
Author: Sydney Smeets ABSTRACT: Concrete is the most universally used building material that defines urban infrastructure. The chemical process to create cement and other ingredients that form this artificial rock are highly carbon intensive. It is only through rethinking this material, its chemical properties, and our reliance on it that the building industry can lower…
