The new goals will be submitted to the U.N.'s climate agency as part of an international agreement where nations publish how they intend to reduce their greenhouse gas emissions, known as nationally determined contributions. The U.S. hopes to achieve “net zero” by 2050, and China by 2060. Indian policymakers say that together with net zero, the country is also trying to ensure energy independence and energy security. That is probably why it has not yet set a peak year for its coal production.  The Benefits of Renewables and Low Carbon Feasibility Undertaking a renewables and low carbon feasibility will allow the organisation’s current environmental and energy performance to be analysed. These results will then form the basis for improvement recommendations, and especially how renewable energy options can be adopted by the site. By installing a renewable asset onsite, the organisation gains a level of energy security and predictability, and potentially an additional revenue stream i

PV Panel recycling technologies

Image
  Solar power is booming, with millions of metric tons of solar panels being produced each year. A panel has a projected lifespan of about 25 years, which means that today’s new solar farms will go out of service in the late 2040s. Most of the weight in a solar panel, about 75 percent, is glass, aluminum, with 10 percent; wiring in a junction box, at 5 percent; and silicon, with just 3.5 percent. Dedicated recyclers are needed, the authors write, to do a more thorough job of recycling all the components of a panel—including the crystalline silicon in the photovoltaic cells themselves. Silicon wafers account for about half the cost of a panel, as well as over half the energy and carbon footprint of manufacturing a panel. But silicon isn't currently being targeted for recycling much because the recovered silicon isn't pure enough to go straight back to a wafer manufacturer. Studies show that the impurity levels are an important issue during the recycling processes.  The resulting
