The automotive industry is already taking positive steps to address this issue—the recent announcement by Toyota of a solar array to provide electricity to power the hybrid Auris production facility and wind power at the Nissan Leaf plant are excellent examples of this. —Greg Archer, LowCVP Managing Director.
This despite evidence that suggests air pollution impacts from the transportation sector exceed those from greenhouse gases. … solar, wind, hydroelectric, and nuclear) as compared to the eastern US (EUS), where the electricity market is dominated by pollutant and precursor emitting combustion sources (i.e.,
Seaweeds accumulate trace metals in such an efficient way that this process is sometimes used to clean up polluted harbors. It would be transformative if we could harness that capability to harvest the critical rare earths we need for a net-zero economy in a low-impact way using this natural ability.
The NH 2 tractor is a 106 hp (79 kW) working prototype able to perform all the tasks of a tractor while operating virtually silent and emitting zero pollutants. Farmers have the space to install alternative electricity generation systems, such as solar, wind, biomass or waste, and then store that power as hydrogen.
China, the world’s largest pollution emitter, is going green with clean energy alternatives and doing so quickly. Recent energy reports detail the nation’s commitment to implementing solar and wind power, so much so that it is expected to achieve its 2030 clean energy targets by the end of the month.
Biomass and solar are shown as primary energy due to their multiple uses. Wind energy, including on- and offshore systems. However, if environmental impacts such as emissions of pollutants and greenhouse gases were monetized and included in energy prices, more renewable energy technologies may become economically attractive.
These efforts will likely be achieved through continued renewable and clean energy development, infrastructure overhaul, new limits on pollutants and through the establishment or broader adoption of resource and environmental taxes, along with plans to introduce pilot cap-and-trade mechanisms for both carbon and various pollutants.
Cutting pollution and global heating emissions in the United States is dependent more than anything else on 1) shifting from fossil fuel powered vehicles to electric vehicles and human-powered transit, and 2) switching from coal and natural gas to solar and wind energy.
