The charts below show the number of global patents filed not granted for renewable energy technologies. These are differentiated by technology type e. Note that figures for may be subject to a time lag; processing times of patent applications vary and some patents submitted over this period may not yet be recorded in statistics.
These figures will be updated with time if additional patent applications are recorded. The chart below shows the share of final energy consumption which is inclusive of electricity, transport, heating and cooking derived from renewables plotted against income GDP per capita, adjusted for cross-country price differences.

Here we see that at very low incomes, the majority of final energy is derived from renewables — this is predominantly in the form of traditional biomass for cooking and heating. Continued economic development through low-to-middle and into higher incomes has historically been achieved for most countries through industrialisation, and as a result a dominance of fossil fuels within the energy mix.
A Complete Guide to 7 Renewable Energy Sources
This is shown by the continued decline in renewables as a share of final energy. As countries approach upper middle to high-incomes, we tend to see a trough in this trend as investment in renewables increases and the share begins to rise again. This progress is much more noticeable for some countries than others: Denmark, Austria and Sweden, for example, show this bottom plateau then rising trend clearly. Others, such as Canada, the United States and Australia show much flatter trends.
Renewable Energy vs Fossil Fuels: 5 Essential Facts
The cost of solar PV has fallen substantially in recent decades, as shown in the chart below. Here we see the cost of solar PV modules in dollars per watt-peak of energy output 2 versus the global cumulative capacity of solar PV. This trend is used for calculation of a learning rate; this provides an indication of the level of cost reduction as manufacturers and producers accumulate experience through technology deployment.
The price of solar PV modules has fallen more than fold since On average, the technology has had a learning rate of 22 percent; this means that the cost falls by 22 percent for every doubling in solar PV capacity although progress has not necessarily been constant over this period.
To maintain consistency between metrics and sources, we have attempted to normalise all energy data to units of watt-hours Wh , or one of its SI prefixes. The table below shows the conversion of watt-hours to the range of SI prefixes used. This website provides the results of CROP evaluations Exit that have been conducted for more than 50 million acres of public forestlands potentially vulnerable to wildfires.
The evaluations contain detailed resource-offering maps and quantify the biomass available for removal within five years. This online tool provides access to the National Forest Inventory and Analysis databases.
It can be used to generate tables and maps of forest statistics by running standard reports for a specific state or county and survey year, or customized reports based on criteria selected by the user. This report assesses the market potential for biogas energy projects at swine and dairy farms in the United States. For the top ten swine and dairy states, the guide characterizes the sizes and types of operations where biogas projects are technically feasible, along with estimates of potential methane production, electricity generation, and greenhouse gas emission reductions.
The U. It allows homeowners, installers, manufacturers, and researchers to easily develop estimates of the performance of hypothetical PV installations. Solar Powering America , offers a resource list of federal government solar power resources for state and local governments. A Solar Power Purchase Agreement SPPA is a financial arrangement in which a third-party developer owns, operates, and maintains a photovoltaic PV system, and a customer hosts the system on its property and purchases the system's electric output for a predetermined period. EPA's Green Power Partnership is working with stakeholders to identify economic and administrative barriers in the deployment of on-site renewable energy projects.
The toolbox website examines six key issues that have important implications for developing on-site solar projects, identifies key resources, and addresses major questions and hurdles sustainability experts have identified as information gaps or obstacles in their development of new on-site solar projects.
Local governments will find project development resources and learn from industry experts and their peers. DOE's Wind Program is part of the federal government's effort to support the increased deployment of wind energy facilities on public, private, and tribal lands, airspace, and offshore. This site is a resource for information on the siting of wind turbines and Federal activities to support the increased deployment of wind energy. Department of Energy Wind Program's platform for disseminating credible information about wind energy.
The purpose of WINDExchange is to help communities weigh the benefits and costs of wind energy, understand the deployment process, and make wind development decisions supported by the best available information. Contact Us to ask a question, provide feedback, or report a problem.
