题目Despite modem society's heavy dependence on fossil fuels for energy, most people are aware that the supply of these fuels is finite (有限的). As oil, in particular, becomes more costly and difficult to find, researchers are looking at alternative energy sources, including...
aSolar energy development provides an excellent opportunity to replace expensive fossil fuels in situations where the demand is remote and distributed, and where grid development and centralized generation are not possible. As scale increases, new supply chains and business models will develop, and ...

fiber, but the remaining four products within the COOLMAX line have a decidedly negative impact on the environment. The production of COOLMAX fibers involves formaldehyde, which is a potent neurotoxin. Additionally, all types of polyester are unsustainable since they are made using fossil fuels. ...
The cultivation of plant-based fibers generally requires the use of chemical pesticides and fertilizers, and the production of synthetic fibers generally requires the use of fossil fuels, and these fibers are not biodegradable. Since animal fibers, such as suede, are renewable and biodegradable, ...
800 degrees.That's hot enough to begin manufacturing cement (水泥) and other industrial products—processes that typically rely on burning fossil fuels—and to potentially cut up to 10 percent of global greenhouse gas emissions.(由总部位于帕萨迪纳的Heliogen公司制造,每个16平方英尺...
