The NREL dedicates to develop renewable energy and energy efficiency technologies and practices, advances related science and engineering, and transfer knowledge and innovations to address the nation’s energy and environmental goals.
Fixed-price subsidy system, quota system, energy tax, franchise, financial subsidies and public benefit funds are commonly used institutional tools for new energy area and key strategies for advancing new energy development.
First, it is necessary to keep tracing the trend of new energy policies and standards of the developed countries and introduce the advanced international practice to improve the new energy development supporting policy system suitable for China.

As the crack advanced, energy was dissipated by the frictional pull-out of the bridging CNTs from the matrix, reducing the cyclic crack propagation rate.
As strain advanced, dislocation tangles moved gradually towards the grain boundaries.
