Art is omnipresent, in various forms of music, the written word or painted pictures. Shaped beautifully out of an ugly rock or coloured on a blank canvas, there are various ways in which art is seen. In this article, we cover the prominent forms of visual arts that the world has been witnessing since many ages. From the age-old primitive arts to the contemporary forms of it, art has travelled and transformed many worlds. The aim of this article is also to help you better identify or associate with a style of art, the next time you see something.Abstract art: As the name defines it, artists here do not believe that showing specific objects is of importance. Shape, forms and colour thus take precedence and the flow of emotions is considered important. This has also been considered similar to non-figurative art, non objective art and other such styles.Cubism: Here artists make use of geometric shapes to create images. Paintings often do not look real, but reflect the beauty of shapes. Led by artists like Picasso, these paintings focused on the art in shapes. Portraits were often deconstructed to the two-dimensional surface and diverse viewpoints considered for creating art.Expressionism: More that the size and shape of the picture, artists here work to bring across expressions, and hence the name. Artists would thus penetrate into the inner state of things of the outer world.Fauvism: This art form made use of non-naturalistic colours with works often being painted directly from nature. These paintings used bright colours and forms, initially shocking viewers and causing critics to call them ‘les fauves’ or ‘wild beasts’. The art form emerged in Paris, and the pictures showcased individual artists’ strong personal feelings.Pop Art: The abbreviation of popular art, pop art is a style that is bright, colourful and represents the true elements of an era of consumerism. Images are thus inspired from mediums like advertisements, newspaper headlines, comic strips, black and white pictures and also photographs.Primitive arts: Also known as naïve arts, ethnographic arts, tribal arts, outsider arts or self-taught arts, here pictures look like they have been drawn by a child. The images may be religious or ceremonial in nature and can be on various mediums like stone walls, caves or wooden carvings. This form of art usually shows simple pictures without much artistic detailing.Realism: Images in this form of art are made to appear as they actually are. This means that portraits or scenes are drawn as an objective reality that exists for a third person. Artists thus paint pictures with the right (rather believable) colour combinations to depict people, places or objects.Other than the above forms of art, many more different styles also exist. Some of those overlap with the ones mentioned above, while many are new in presentation, style and form. In our further articles, we will discuss about more new forms. Till then, keep an eye out for the above.

The use of coal contributes to the formation of poisonous gases and environmental pollution, and that’s why people are looking for an alternative sources of energy. In the face of the challenges of climate changing, we are faced with the need to look for alternative energy sources to reduce environmental pollution. One of them is the use of solar energy in the form of solar panels mounted on the roof. They can be used both for heating domestic water and supporting central heating, or can be used as a photovoltaic source of electric energy. From my post, you will learn how to use solar heat and solar panel to get cheap hot water for the own household.

Solar panels

Solar collectors are in the form of mirrors with very large surfaces or a structure consisting of vacuum glass tubes. Panels are mainly installed on the roofs of houses. They catch the rays of light, thus accumulating the energy needed for conversion into thermal energy.

Such a process of accumulating heat is possible thanks to the absorber placed behind the glass or in a glass tube. It absorbs energy from the sun and is connected to a system of copper pipes. The heating-up solar liquid, propylene glycol solution, flows through them, from which the heat is transferred to the utility water.

Benefits of solar thermal panel

The advantages of solar collectors cannot be overestimated because their installation allows, in a completely ecological manner, to obtain heat necessary to hot tap water and to support central heating. Another advantage of solar panel is that they are working without polluting the environment.

Their third advantage is energy efficiency. Solar thermal panel meet up to 70 percent of the annual demand for thermal energy, which is needed to heat domestic hot water, especially in the months from March to the end of October. In the summer, a properly selected solar panels set will cover up to 100 percent of the demand for domestic hot water.

Another advantage of solar collectors is the convenience of their use and trouble-free operation. Correctly mounted on the roof solar panel, will require maintenance around one time per one-two years. Solar panels are versatile devices that can be installed on the roofs of single-family and multifamily houses, as well. Installation of solar panels will increase the value of your house. Now, when you know more about solar panels, you can decide to use them or not. If you are house owner, it is worth to take positive decision and install solar panels or PV panels.
