immediate action to incorporation renewable energy sources is crucial. Specifically‚ the government should stop giving subsidies to oil companies and instead be using taxpayers’ money to develop solar energy‚ such as‚ solar thermal energy in order to establish a sustainable‚ clean‚ responsible and efficient form for energy for generations to come. While solar energy startup and even maintenance costs can be just as expensive as oil and coal production‚ solar energy is undoubtedly worth the price in the

GASEOUS DISCHARGE LAMPS: A gaseous discharge lamp is essentially a glass or quartz envelop containing two electrodes and a small quantity of gas or vapour at a low pressure. In these lamps light is obtained by applying an electric potential difference to a gas or vapour contained by the lamp under a suitable pressure. Due to application of electric potential difference gas gets ionised and an electric current flows; the tube is filled with a luminous discharge. The light spectrum

only that it’s available and plentiful. Electricity generated by burning fossil fuels such as coal‚ oil and natural gas‚ emits carbon dioxide‚ nitrogen oxides and sulfur oxides -- gases scientists believe contribute to climate change. Solar thermal (heat) energy is a carbon-free‚ renewable alternative to the power we generate with fossil fuels like coal and gas. This isn’t a thing of the future‚ either. Between 1984 and 1991‚ the United States built nine such plants in California’s Mojave Desert‚ and

Direct energy conversion system Direct energy conversion systems that could operate in the 100-700°C temperature range with high efficiencies (>30%) provide an attractive compact alternative to internal combustion engines for many military applications. They will also expand the possibilities for waste heat recovery applications. The core of the solution we are proposing is a metal/semiconductor nanocomposite that will allow us to modify four intrinsic material properties in order to fabricate
