The White House on Wednesday plans to announce new measures to support the development of new U.S. nuclear power plants, a large potential source of carbon-free electricity the government says is needed to combat climate change.

The suite of actions, which weren't previously reported, are aimed at helping the nuclear power industry combat rising security costs and competition from cheaper plants powered by natural gas, wind and solar.

President Joe Biden is expected to quadruple tariffs on electric vehicles from China from roughly 25% to 100%, and raise other tariffs on key industries including semiconductors, solar, and batteries in an announcement Tuesday, according to a source familiar with the decision.

U.S. President Joe Biden is set to announce new China tariffs as soon as Tuesday, targeting sectors including electric vehicles, medical supplies and solar equipment, according to people familiar with the matter.

The expected move by the Biden administration comes ahead of the November presidential election. Biden, a Democrat seeking re-election, has taken a tough-on-China approach that would maintain existing tariffs on many Chinese goods set by former President Donald Trump, his expected Republican challenger.

The White House is set to announce new China tariffs as soon as next week, with a levy on electric vehicles and other clean energy goods.

The full announcement is expected on Tuesday and will target solar goods, critical minerals, and batteries from China, according to reporting from the Wall Street Journal. The Biden administration has invested in these industries domestically. The White House did not respond to a request for comment.

The world’s two most powerful countries, the United States and China, are meeting this week in Washington to talk about climate change. And also their relationship issues.

On this 54th Anniversary of America's first Earth Day celebration, it is a time to reflect on how we moved from a consensus on the urgent need for environmental protection across the country to woefully underestimating the need for action about climate change.

As the world turns its attention to the environment we share on this Earth Day, the tide of public opinion is turning toward decisive climate action. Statewide carbon-neutral goals, emerging carbon credit markets and incentive programs for renewable energies are quickly becoming the new reality.

April 22 marks the 54th celebration of Earth Day. Unfortunately, there should be much more to celebrate five decades later. 

March 20 (Reuters) - U.S. efforts to build a domestic supply chain for solar energy components is stalled and will require urgent government action to support the factories needed to compete with China, according to a report published on Wednesday.

The analysis by Guidehouse Insights, commissioned by the Solar Energy Manufacturers for America Coalition, said existing federal subsidies and trade policies are not enough to help U.S. producers succeed in the face of a global glut of solar equipment.

The wave of consolidation that swept through Big Oil in the last few months is expanding to Big Solar.
