House Dems introduce clean energy bill for net zero
Democratic leaders in the House last week introduced the Climate Leadership and Environmental Action for our Nation’s Future Act (the CLEAN Future Act, or H.R. 1512), a nearly 1,000-page piece of climate change–focused legislation establishing, among other things, a federal clean electricity standard that targets a 50 percent reduction in greenhouse gas emissions from 2005 levels by 2030 and net-zero emissions by 2050.
The bill, a draft version of which was released in January 2020, presents a sweeping set of policy proposals, both sector-specific and economy-wide, to meet those targets. The final version includes a number of significant revisions to bring the legislation into closer alignment with President Biden’s climate policy campaign pledges. For example, the bill’s clean electricity standard would require all retail electricity suppliers to provide 80 percent clean energy to consumers by 2030 and 100 percent by 2035. (A six-page fact sheet detailing the updates is available online.)

Silicon doped CH foams are prepared via a thermally induced phase-inversion technique. With poly(4-methyl-1-pentene) as the foam skeleton material, durene/naphthalene as the solvent/nonsolvent system, and SiO2 as the doping materials, Si doped CH polymer foams with density of 25 to 80 mg/cm3 is successfully prepared, and the mass content of Si is <30%. This paper presents the fabrication procedures of Si doped CH polymer foams. The parameters that influence the properties of the foam products are discussed in detail. The thermal stability and structure of Si doped CH foams are also discussed.
