it means graphite conduct electricity whereas diamond doesnt

Graphite is a good conductor of electricity but diamond is not. Each carbon atom in graphite is directly linked to only three carbon atoms through covalent bonds. Therefore, of the four valence electrons in a carbon atom only three are used for bonding and the fourth is relatively free and can move from one carbon atom to other.

oil shale | National Geographic Society

Oil shale is a type of rock that can be burned for energy or fuel. Like traditional petroleum, natural gas, and coal, oil shale and kerogen are fossil fuels. Fossil fuels developed from the remains of algae, spores, plants, pollen, and a variety of other organisms that lived millions of years ago in

Week 3: Solar photovoltaics: 8 PV economics and

In many countries contracts for very large PV systems >500 MW p are currently being sold in auctions for the lowest ‘bid price’. This has resulted in very low prices of under 4p kWh –1 in Mexico, Brazil, the USA, Saudi Arabia and the United Arab Emirates (IRENA, 2017). These prices are truly competitive with conventional fossil-fuelled generation from oil and gas.
