The shift to renewable energy is key to combating climate change and reducing our dependence on fossil fuels. But critics argue it won’t be possible without financial support from the government. How important are special tax breaks and other subsides, and do they really work?
While President Trump has promised to pull the U.S. out of the Paris climate accord, China’s President Xi Jinxing has vowed to continue to tackle climate change and honor his country’s obligations. Will China become the global leader in combating climate change?
Many economists and policy experts believe carbon pricing is the most effective way to deal with global warming. But others argue that carbon pricing is not a silver bullet for dealing with climate change. Here’s why.
Buildings account for almost a third of global greenhouse gas emissions and the U.N. Environment Programme projects that if we continue with business as usual in the building sector, these emissions will double by 2030. Fortunately, green building is on the rise around the world.
If the international community were to fully understand the threat of climate change, and the likely cost of mitigation and adaptation, perhaps we would commit to continued tax breaks and incentives, and propel the renewable energy transition toward completion. In the long run, I am sure this would be less expensive than coping with the consequences of continued growth in greenhouse gas emissions through 2050.
The worldwide transition from fossil fuels to renewable sources of energy is under way, but to integrate all this variable power into the grid, battery storage is key. Researchers around the world are working on developing better and cheaper batteries.
China became the world’s largest carbon polluter in 2006, surpassing the U.S. But it is also rapidly going green through cutting coal use, investing heavily in renewable energy and launching the world’s largest carbon trading system.
Replacing conventional building boilers with electric heat pumps in New York City buildings could substantially increase the viability of renewable energy use in the city, according to a recent study from researchers from the Earth Institute’s Sustainable Engineering Lab.
Cell phones, iPads, laptops, televisions, hybrid cars, wind turbines, solar cells and many more products depend on rare earth metals to function. Will there be enough for us to continue our high-tech lifestyle and transition to a renewable energy economy?
