First sort, then refurbish
Switzerland’s building stock is quite impressive. There are around 1.8 million buildings in the country, but only one percent of this building stock is renovated each year. In other words, it will take 100 years for the entire building stock in the country to be renovated – which would be too slow to achieve the energy transition. But before politicians decide on stimulating subsidies, this daunting task must first be structured: Which measures make sense for which buildings? And where to start?

Key Improvements to Efficiency and Safety Will Enable Expansion of Nuclear Energy
Nuclear power plants produce about 20% of the United States’ electricity. In order to increase the amount of carbon dioxide-free energy these plants can yield, improvements in efficiency and safety must be made. With support from $1.5 million in grants from the Department of Energy (DOE), researchers at Rensselaer Polytechnic Institute will lead projects aimed at upgrading nuclear power plants with those goals in mind. The grants are part of more than $61 million in awards recently announced by the DOE to support nuclear energy research.
Hydrogen Technologies Take Leading Role Toward Net Zero
Achieving Net Zero energy, where the total amount of energy used is equal to the amount of renewable energy created, is closer than ever before, and hydrogen technologies will play an important role in achieving that goal, but needs and gaps need to be addressed before a true hydrogen-powered future can take form. There are many opportunities in the global public and private sectors for research, development, and deployment collaboration.
Powering Navigational Buoys With Help of Ocean Waves
Traditionally used energy harvesting technologies, like photovoltaic panels or wind turbines, suffer from several limitations. In the absence of daylight and wind, neither of the two can supply any power. In the case of ocean buoys, a potential solution is omnipresent: wave energy. Abundant, predictable, and consistent, the ocean’s waves can be used to power navigation buoys. Researchers have developed sphere-based triboelectric nanogenerators that can be incorporated directly into navigational buoys to provide electricity from ocean waves.
Measuring Photovoltaic Performance Indoors
As photovoltaic technology continues to progress, PV devices’ applications in harvesting energy from indoor ambient light have become more realistic. Some combinations of PV material and light source can be more efficient in converting power than the same material under solar illumination, and a better understanding of these relationships is needed to fully characterize the behavior of solar cells under very low illumination conditions.
