Geothermal energy harnesses steam trapped in underground reservoirs to generate electricity with minimal environmental impact compared to other energy sources. It works by tapping into reservoirs of steam trapped in hot rocks deep underground, which can then power steam turbines or be used in binary plants that use the steam to boil a secondary fluid to drive the turbines. While the initial costs are high and drilling is difficult, geothermal energy has a small land footprint, is virtually limitless, simple, and reliable once operational. Prime locations for geothermal energy in the U.S. include The Geysers reservoir in California.

The Future of Natural Gas
Natural gas has advantages as an energy source as it is cheap to produce in large quantities from landfills and does not leave ash, making it more environmentally friendly than some alternatives. However, it has a lower energy density than other fuels so transporting and storing significant quantities requires large tanks. Overall natural gas appears to have benefits but infrastructure challenges that must be addressed for widespread adoption.
Adding Value with Green Roofs by Kirstin Weeks
This document discusses the benefits of green roofs and provides information about their costs and performance. It summarizes that green roofs can provide stormwater management benefits like retaining 30-100% of rainfall, reduce energy costs for buildings by around $0.17 per square foot annually, and provide habitat. Installation costs range from $10-20 per square foot depending on the type of green roof. A case study found that over 30 years, a green roof can have a positive net present value of $2.70 per square foot and payback period of 6.2 years. The document advocates for policies to promote green roofs in San Francisco.

Este documento describe los enfoques cualitativo y cuantitativo de investigación, así como el enfoque mixto que surge de la combinación de ambos. Explica que el enfoque cualitativo implica la interacción con los sujetos de estudio y el uso del investigador como instrumento de medición, mientras que el enfoque cuantitativo busca la comprensión y predicción objetiva de la realidad a través de métodos estadísticos. Finalmente, concluye que ambos enfoques son valiosos para generar nuevos conocimientos científicos

The document discusses an electronic health record system called Healthcare Gateway that allows users to access and store their medical records online. It can be accessed through a registered account or smart card. The system stores a user's complete medical history from different hospitals and labs, and allows sharing records with doctors. It aims to provide easy access to medical data during emergencies by eliminating the need to physically carry records.

Hydro electric energy
Hydroelectric energy is produced by harnessing the gravitational force of falling or flowing water to turn turbines that generate electricity. It is produced in 150 countries, with China being the largest producer and accounting for around 17% of its domestic electricity. The pros of hydroelectricity include being renewable, low-cost, flexible, clean without CO2 emissions, reliable, and controllable; the cons include requiring large dams that can damage environments and marine life. Hydroelectric plants work by creating reservoirs through dams, channeling water through tunnels to turn turbines and generate electricity.
Geothermal energy
Geothermal energy harnesses steam reservoirs trapped in hot rocks below the Earth's surface. It has a very small environmental impact and is a reliable and cheap source of energy. Geothermal plants convert steam from reservoirs into electricity through dry steam or binary cycle plants. While it has a small land footprint and is virtually limitless, geothermal energy has high initial costs to drill wells and uses water. The largest geothermal site in the US is The Geysers in California.
