What is solar energy

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.^[1]^[2]

It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.

The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,575–49,837 exajoules (EJ). This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012.^[3]^[4]

In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries' energy security through reliance on an indigenous, inexhaustible, and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating global warming, and keep fossil fuel prices lower than otherwise. These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared".

Getting Started With Web Design - What is Web Design, and What Skills Do You Need?

This is a guide for any individual who needs to take the primary, little strides to turn into a website specialist. Before we get into how you can approach figuring out how to configuration pages, it merits clarifying what a website specialist does: o A website specialist controls the inventive plan of pages, typically working with a customer who will determine the novel needs and usefulness for their web-page. The objective of any web specialist is to make one of a kind and wise plan dependent on the customer's necessities. Really basic, correct? Website architecture at its most fundamental works in the very same manner as some other sort of configuration work. A website specialist is an unbelievably significant piece of the way toward making a site. Regardless of how great the programming or substance of a site, in the event that it hasn't been planned appropriately it can without much of a stretch lose any possible traffic.
